chore: apply ESLint auto-fix across entire backend

Reformats code style (line breaks, indentation, type annotations)
without changing logic. Also includes minor feature additions bundled
in the same lint run (stats service, user-settings groups, agrarmonitor
polling improvements).

+# Label-Print-Agent – Architektur & Implementierungsreferenz
+
+Dieses Dokument beschreibt vollständig das Label-Print-Agent-System aus dem Paperless Manager. Es dient als Grundlage für die Reimplementierung in einem anderen Projekt.
+
+---
+
+## 1. Systemübersicht
+
+Das System ermöglicht es, **Etiketten-Templates** zu definieren (mit Layout, Variablen-Feldern und Abmessungen) und daraus **Druckjobs** zu erzeugen, die von einem oder mehreren **Print Agents** abgeholt und gedruckt werden.
+
+### Beteiligte Komponenten
+
+| Komponente | Aufgabe |
+|---|---|
+| **Frontend** | Template-Verwaltung, Job-Erstellung, Label-Vorschau |
+| **Backend API** | REST-Endpunkte, Job-Queue, Rendering |
+| **Datenbank** | Persistenz für Templates und Jobs |
+| **LabelRenderer** | SVG → PNG (300 DPI) |
+| **Print Agent** | Eigenständiger Client, der Jobs abholt und druckt |
+
+### Datenfluss (ASCII)

+## 2. Datenmodelle
+
+### 2.1 LabelTemplate (in PM: Teil des `BarcodeTemplate`)
+
+Für das neue Projekt empfiehlt sich eine eigenständige `LabelTemplate`-Entity:
+
+```typescript
+export interface LabelInputField {
+  name: string;       // Technischer Feldname (Variablenname)
+  label: string;      // Anzeigetext im Formular
+  type: 'text' | 'number' | 'date';
+}
+
+export type LabelElement =
+  | {
+      type: 'text';
+      content: string;    // Inhalt, kann {variablenname} enthalten
+      x: number;          // X-Position in mm ab linker Kante
+      y: number;          // Y-Position in mm ab oberer Kante
+      fontSize: number;   // Schriftgröße in mm
+      bold?: boolean;
+      align?: 'left' | 'center' | 'right';
+      maxWidth?: number;  // Maximale Breite in mm (Text wird gestreckt/gestaucht)
+    }
+  | {
+      type: 'qr';
+      content: string;    // QR-Inhalt, kann {variablenname} enthalten
+      x: number;          // X-Position in mm
+      y: number;          // Y-Position in mm
+      sizeMm: number;     // Quadratische Größe in mm
+    }
+  | {
+      type: 'line';
+      x1: number; y1: number;  // Startpunkt in mm
+      x2: number; y2: number;  // Endpunkt in mm
+      lineWidth?: number;      // Linienbreite in mm (default: ~0,085mm = 1px bei 300DPI)
+    };
+
+// TypeORM Entity (vereinfacht)
+@Entity('label_templates')
+export class LabelTemplate {
+  @PrimaryGeneratedColumn()
+  id: number;
+
+  @Column({ length: 100 })
+  name: string;
+
+  @Column({ type: 'int', default: 57 })
+  widthMm: number;           // Etikettenbreite in mm
+
+  @Column({ type: 'int', default: 32 })
+  heightMm: number;          // Etikettenhöhe in mm
+
+  @Column({ type: 'simple-json', nullable: true })
+  inputFields: LabelInputField[] | null;  // Formularfelder
+
+  @Column({ type: 'simple-json', nullable: true })
+  layout: LabelElement[] | null;          // Etikett-Elemente
+
+  @Column({ length: 1000, nullable: true })
+  getUrl: string | null;       // URL zur Nummernreservierung (GET, {var} möglich)
+
+  @Column({ length: 1000, nullable: true })
+  printedUrl: string | null;   // Callback nach erfolgreichem Druck (POST)
+
+  @Column({ length: 1000, nullable: true })
+  releaseUrl: string | null;   // Callback bei Druckfehler (POST)
+
+  @CreateDateColumn()
+  createdAt: Date;
+
+  @UpdateDateColumn()
+  updatedAt: Date;
+}
+```
+
+### 2.2 LabelPrintJob
+
+Die DB-Tabelle fungiert als **persistente Job-Queue**.
+
+```typescript
+// Originaldatei: paperless-backend/src/database/entities/label-print-job.entity.ts
+
+@Entity('label_print_jobs')
+export class LabelPrintJob {
+  @PrimaryGeneratedColumn()
+  Id: number;
+
+  @Index()
+  @Column({ type: 'varchar', length: 20, default: 'pending' })
+  Status: 'pending' | 'printed' | 'error';
+
+  @Column({ type: 'mediumblob', nullable: true })
+  LabelImageData: Buffer | null;   // Lazy-rendered PNG (kann null sein bis Claim)
+
+  @Column({ type: 'int' })
+  LabelWidthMm: number;
+
+  @Column({ type: 'int' })
+  LabelHeightMm: number;
+
+  @Column({ type: 'int', nullable: true })
+  BarcodeTemplateId: number | null;  // Referenz auf Template (ohne FK-Constraint)
+
+  @Column({ type: 'simple-json', nullable: true })
+  LabelVariables: Record<string, string> | null;  // Aufgelöste Variablen zum Druckzeitpunkt
+
+  @Index()
+  @Column({ type: 'datetime', nullable: true })
+  LockedAt: Date | null;           // Zeitstempel des Locks
+
+  @Column({ length: 255, nullable: true })
+  LockedByAgent: string | null;    // Agenten-ID (z.B. "BUERO-PC")
+
+  @Column({ type: 'datetime', nullable: true })
+  PrintedAt: Date | null;
+
+  @Column({ length: 255, nullable: true })
+  PrintedByAgent: string | null;
+
+  @Column({ length: 255, nullable: true })
+  PrinterName: string | null;
+
+  @Column({ type: 'text', nullable: true })
+  ErrorMessage: string | null;
+
+  @CreateDateColumn()
+  CreatedAt: Date;
+}
+```
+
+**Wichtig:** `LabelVariables` speichert die bereits aufgelösten Variablen zum Zeitpunkt der Job-Erstellung. Das Template-Layout kann sich danach ändern — der Job verwendet trotzdem die ursprünglichen Werte.
+
+---
+
+## 3. API-Endpunkte
+
+Alle Endpunkte unter `/api/label-print-agent`:
+
+### Frontend-Endpunkte (erfordern Authentifizierung)
+
+#### `POST /preview` — Label-Vorschau rendern
+
+Rendert ein PNG ohne DB-Eintrag. Zum Testen von Layouts.
+
+```
+Request:  { templateId: number, fieldValues?: Record<string, string> }
+Response: image/png (Buffer)
+```
+
+#### `POST /jobs` — Druckjob erstellen
+
+```
+Request:  { templateId: number, fieldValues?: Record<string, string> }
+Response: { jobId: string }
+Status:   201 Created
+```
+
+### Agent-Endpunkte
+
+#### `GET /events` — SSE-Stream (Server-Sent Events)
+
+Agent hält diese Verbindung dauerhaft offen. Bei neuem Job erhält er eine Notification.
+
+```
+Response: text/event-stream
+Payload:  { type: 'label-job-available' }
+Header:   X-Accel-Buffering: no  (wichtig für nginx-Reverse-Proxy)
+```
+
+#### `GET /jobs/next?agentId=MEIN-PC` — Nächsten Job beanspruchen
+
+```
+Response 200: {
+  jobId: string,
+  labelImageBase64: string | null,  // PNG als Base64
+  labelImageContentType: 'image/png',
+  labelWidthMm: number,
+  labelHeightMm: number
+}
+Response 204: (kein Job verfügbar)
+```
+
+#### `GET /jobs/:id/image` — Job-Bild separat abrufen
+
+```
+Response: image/png (Buffer)
+```
+
+#### `POST /jobs/:id/printed` — Job als gedruckt markieren
+
+```
+Request:  { agentId?: string, printerName?: string }
+Response: { ok: true }
+```
+
+#### `POST /jobs/:id/error` — Druckfehler melden
+
+```
+Request:  { agentId?: string, printerName?: string, errorMessage?: string }
+Response: { ok: true }
+```

+      sansSerifFamily: 'Liberation Sans',
+    },
+  });
+  return Buffer.from(resvg.render().asPng());
+}
+```
+
+### Bekannte Eigenheiten
+
+- **Baseline-Problem:** `librsvg` (verwendet von `@resvg/resvg-js`) ignoriert `dominant-baseline`. Daher muss zur Y-Koordinate die Schriftgröße addiert werden, damit die **Oberkante** des Textes der eingegebenen Y-Position entspricht (s. `yBaseline`-Berechnung).
+- **Schriften:** Auf Systemen ohne `Liberation Sans` (z.B. Windows) fällt die Bibliothek auf Arial zurück. Für plattformübergreifende Konsistenz können Schriften auch per Buffer eingebettet werden.
+- **QR-Code:** `errorCorrectionLevel: 'M'` ist ein guter Kompromiss zwischen Fehlertoleranz und Dichte.

+## 6. Variablen-System
+
+### Template-Syntax
+
+| Syntax | Bedeutung | Beispiel |
+|---|---|---|
+| `{feldname}` | Wert des Feldes | `{name}` → `Müller GmbH` |
+| `{feldname:6}` | Zero-padded auf N Stellen | `{nr:6}` → `000042` |
+| `{datum}` (date-Feld) | Formatiert als `dd.MM.yyyy` | `{datum}` → `15.05.2026` |
+| `{datum.year}` | Nur das Jahr | `{datum.year}` → `2026` |
+| `{datum.month}` | Nur den Monat | `{datum.month}` → `05` |
+| `{datum.day}` | Nur den Tag | `{datum.day}` → `15` |
+| `{number}` | Reservierte Nummer (via GetUrl) | `{number}` → `1234` |
+
+### URL-Templates
+
+Die Felder `LabelGetUrl`, `LabelPrintedUrl`, `LabelReleaseUrl` unterstützen ebenfalls Variablen-Substitution:
+
+```
+LabelGetUrl:     https://api.example.com/numbers/next?batch={batch}
+LabelPrintedUrl: https://api.example.com/numbers/{number}/confirm
+LabelReleaseUrl: https://api.example.com/numbers/{number}/release
+```
+
+**Sicherheitscheck:** Nur `http://` und `https://` werden akzeptiert.

+
+## 8. NestJS-Modul-Setup
+
+```typescript
+// label-print-agent.module.ts
+@Module({
+  imports: [
+    TypeOrmModule.forFeature([LabelPrintJob, LabelTemplate]),
+  ],
+  controllers: [LabelPrintAgentController],
+  providers: [LabelPrintAgentService, LabelRendererService],
+})
+export class LabelPrintAgentModule {}
+```
+
+---
+
+## 9. Empfehlungen für das neue Projekt
+
+### Architektur übernehmen
+
+Das Muster **DB als Queue + SSE als Push + Polling als Fallback** ist einfach und robust. Es benötigt keine externe Message-Queue (Redis, RabbitMQ etc.) und funktioniert gut für geringe bis mittlere Job-Volumina.
+
+### Locking-Strategie
+
+| Szenario | Empfehlung |
+|---|---|
+| Ein Agent | Optimistic Lock (5-Min-TTL) reicht aus |
+| Mehrere Agents, wenige Jobs | Optimistic Lock reicht aus |
+| Viele Agents, hoher Durchsatz | DB-Row-Lock (`SELECT ... FOR UPDATE`) oder Redis-Lock |
+
+### Rendering-Alternativen
+
+| Umgebung | Alternative |
+|---|---|
+| Node.js | `@resvg/resvg-js` + `qrcode` (wie hier) |
+| Node.js (Docker) | Puppeteer (HTML → PNG/PDF, braucht Chrome) |
+| Python | `reportlab` oder `cairosvg` |
+| Kein Node.js | Server-seitiges Rendering via separatem Microservice |
+
+### SSE-Alternativen
+
+| Alternative | Wann |
+|---|---|
+| SSE (wie hier) | Einfachste Lösung, funktioniert durch nginx |
+| WebSocket | Wenn bidirektionale Kommunikation nötig ist |
+| Polling-only | Wenn der Agent kein persistentes HTTP unterstützt |
+
+### Template-Verwaltung im neuen Projekt
+
+Im Paperless Manager sind Label-Templates Teil der `BarcodeTemplate`-Entity (historisch gewachsen). Für ein neues Projekt empfiehlt sich eine **eigenständige `LabelTemplate`-Entity** ohne nicht-Label-relevante Felder — das vereinfacht CRUD und API erheblich.
+

+
+## 11. Frontend-UI: Template-Editor (SettingsPage)
+
+**Originaldatei:** `paperless-frontend/src/pages/SettingsPage.tsx`
+
+Der Template-Editor ist ein **Modal-Formular** (720px breit) mit Ant Design. Er enthält zwei eigenständige React-Komponenten.
+
+### Komponenten-Übersicht
+
+| Komponente | Zweck |
+|---|---|
+| `BarcodeTemplatesTab` | Tabelle mit allen Templates + CRUD-Logik |
+| `LabelElementRow` | Eine Zeile im Layout-Editor (typ-abhängige Felder) |
+
+---
+
+### BarcodeTemplatesTab
+
+Verwaltet den gesamten Template-Lebenszyklus. State:
+
+```typescript
+const [data, setData] = useState<BarcodeTemplate[]>([]);
+const [editing, setEditing] = useState<BarcodeTemplate | null>(null);
+const [previewUrl, setPreviewUrl] = useState<string | null>(null);
+const [testPrinting, setTestPrinting] = useState(false);
+const [form] = Form.useForm();
+```
+
+**Formular-Initialwerte** (beim Neu-Anlegen):
+
+```typescript
+form.setFieldsValue({
+  SplitBefore: false,
+  DateinameTemplate: '',
+  LabelEnabled: false,
+  LabelWidthMm: 57,       // Standard: DYMO 57mm
+  LabelHeightMm: 32,
+  LabelInputFields: [],
+  LabelLayout: [],
+});
+```
+
+**Testetikett-Funktion** (`handleTestLabel`):
+
+```typescript
+const handleTestLabel = async () => {
+  const values = await form.validateFields();
+  await barcodeTemplatesApi.update(editing.Id, values);  // erst speichern
+
+  // Auto-Testwerte für alle Felder generieren
+  const testFieldValues: Record<string, string> = {};
+  const today = new Date().toISOString().slice(0, 10);
+  for (const f of values.LabelInputFields ?? []) {
+    if (f.type === 'date') testFieldValues[f.name] = today;
+    else if (f.type === 'number') testFieldValues[f.name] = '1';
+    else testFieldValues[f.name] = 'Test';
+  }
+
+  const url = await labelPrintAgentApi.previewLabel(editing.Id, testFieldValues);
+  setPreviewUrl(url);  // öffnet zweites Modal mit PNG
+};
+```
+
+**Modal-Footer-Buttons:**
+
+```
+[Testetikett erstellen]   [Abbrechen]   [Speichern]
+         ↑
+  Nur sichtbar wenn bestehende Vorlage (editing && !isNew)
+```
+

+  └──────────────────────────────────────────────────────────────┘
+```
+
+**Platzhalter-Chips werden live berechnet:**
+
+```typescript
+// Aus den aktuellen LabelInputFields dynamisch erzeugt
+const chips: string[] = [];
+for (const f of inputFields) {
+  chips.push(`{${f.name}}`);
+  if (f.type === 'date') {
+    chips.push(`{${f.name}.year}`, `{${f.name}.month}`, `{${f.name}.day}`);
+  }
+}
+const chipsWithNumber = [...chips, '{number}'];
+// → wird als `extra`-Text bei URL-Feldern und Layout-Elementen angezeigt
+```
+
+---
+
+### LabelElementRow (je Layout-Element eine Card)
+
+Typ wird per `Form.useWatch` reaktiv ausgelesen → zeigt typ-spezifische Felder:
+
+```typescript
+const type = Form.useWatch(['LabelLayout', listName, 'type'], form);
+```
+
+**Typ: Text**
+
+```
+[X mm] [Y mm] [Schrift (mm)] [Max. Breite (mm)] [Fett ☐] [Ausrichtung ▼]
+[Inhalt: Input mit Platzhalter-Hinweis "{nummer} oder {datum}"]
+```
+
+Default beim Hinzufügen: `{ type: 'text', x: 0, y: 0, fontSize: 3, content: '', bold: false }`
+
+**Typ: QR-Code**
+
+```
+[X mm] [Y mm] [Größe (mm)]  [Inhalt: Input mit "{number}"]
+```
+
+Default: `{ type: 'qr', x: 0, y: 0, sizeMm: 20, content: '' }`
+
+**Typ: Linie**
+
+```
+[X1 mm] [Y1 mm] [X2 mm] [Y2 mm] [Stärke (mm, step: 0.1)]
+```
+
+Default: `{ type: 'line', x1: 0, y1: 0, x2: 50, y2: 0 }`
+
+Jede Card hat rechts oben einen Löschen-Button (`DeleteOutlined`).
+
+---
+
+### Vorschau-Modal
+
+Nach „Testetikett erstellen" öffnet sich ein zweites Modal (520px) mit dem gerenderten PNG:
+
+```tsx
+<Modal title="Etikett-Vorschau" width={520}>
+  <div style={{ background: '#e0e0e0', padding: 24, display: 'flex', justifyContent: 'center' }}>
+    <img src={previewUrl} style={{ maxWidth: '100%', boxShadow: '0 2px 8px rgba(0,0,0,0.3)' }} />
+  </div>
+</Modal>
+```
+
+Das `previewUrl` ist ein `URL.createObjectURL(blob)` — muss mit `URL.revokeObjectURL()` beim Schließen freigegeben werden.
+
+---
+
+## 12. Frontend-UI: Druck-Dialog (InboxPage)
+
+**Originaldatei:** `paperless-frontend/src/pages/InboxPage.tsx`
+
+### Einstiegspunkt
+
+Button in der Toolbar der InboxPage:
+
+```tsx
+<Button icon={<PrinterOutlined />} onClick={openPrintDialog}>
+  Etikett drucken
+</Button>
+```
+
+### openPrintDialog
+
+Lädt beim Öffnen parallel Templates und User-Settings (für Standard-Template):
+
+```typescript
+const openPrintDialog = async () => {
+  const [all, settings] = await Promise.all([
+    barcodeTemplatesApi.list(),
+    userSettingsApi.get(),
+  ]);
+  const enabled = all.filter((t) => t.LabelEnabled);  // nur aktive Templates
+  setLabelTemplates(enabled);
+
+  // Standard-Template aus User-Settings vorauswählen
+  const defaultId = settings.defaultLabelTemplateId;
+  const defaultTemplate = defaultId != null
+    ? (enabled.find((t) => t.Id === defaultId) ?? null)
+    : null;
+  setSelectedTemplate(defaultTemplate);
+  setFieldValues(buildInitialFieldValues(defaultTemplate));
+  setLabelCount(1);
+  setPrintDialogOpen(true);
+};
+```
+
+### Datum-Vorausfüllung
+
+```typescript
+function buildInitialFieldValues(template: BarcodeTemplate | null): Record<string, string> {
+  const today = dayjs().format('YYYY-MM-DD');
+  const values: Record<string, string> = {};
+  for (const field of template?.LabelInputFields ?? []) {
+    if (field.type === 'date') values[field.name] = today;
+    // text- und number-Felder bleiben leer
+  }
+  return values;
+}
+```
+
+### Druck-Modal-Aufbau

+
+### Batch-Druck
+
+```typescript
+const handlePrint = async () => {
+  setPrinting(true);
+  for (let i = 0; i < labelCount; i++) {
+    await labelPrintAgentApi.createJob(selectedTemplate.Id, fieldValues);
+    // Erzeugt N separate Jobs sequenziell (selbe fieldValues)
+  }
+  message.success(labelCount === 1 ? 'Druckauftrag erstellt' : `${labelCount} Druckaufträge erstellt`);
+};
+```
+
+---
+
+## 13. Frontend API-Client
+
+**Originaldatei:** `paperless-frontend/src/api/labelPrintAgent.ts`
+
+```typescript
+export const labelPrintAgentApi = {
+  // Job erstellen (von InboxPage)
+  createJob: (templateId: number, fieldValues: Record<string, string>) =>
