refactor: replace AgrarmonitorWebService with connector methods

- Delete agrarmonitor-web.service.ts (HTML-scraping no longer needed)
- Rewrite AgrarmonitorPollingService to call connector directly
  (eingangsrechnungenLivesearch, setEingangsdatum, setLieferscheinNummer)
- Fix quality issues: concurrency guard, customer-sync try/catch,
  tag dedup via Set, parseInt NaN guard, page_size overflow warning
- Update AgrarmonitorModule to import TypeORM/PaperlessModule
- Remove node-html-parser dependency
- Update agrarmonitor-connector to latest Gitea commit
