feat: auto-move imported emails to IMAP folder and add 90-day cleanup

- New ImapFolderService moves emails to configurable "importiert" folder after successful import, creating the folder if it doesn't exist - Daily cron at 03:00 moves emails older than 90 days to trash and empties it - Extract createImapClient() helper in EmailDownloadService - Add ensurePageCache() with in-flight deduplication to BarcodeScannerService - InboxService regenerates page cache on-demand when image file is missing - IMAP_IMPORTED_FOLDER and IMAP_TRASH_FOLDER added to .env.example and docker-compose Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
