Phase 3: Django-natives DMS – Paperless-NGX durch DokumentDatei ersetzt

- Neues Modell DokumentDatei mit PostgreSQL FTS (SearchVectorField, GinIndex)
- Upload-Pfad: dokumente/YYYY/MM/<uuid>/dateiname
- 7 DMS-Views: list, detail, download, upload (HTMX Drag&Drop), delete, edit, search_api
- Templates: list, detail, edit, upload mit Drag&Drop-Zone, Partials
- URLs: /dms/ komplett verdrahtet
- Sidebar: DMS als Primäreintrag, Paperless als Legacy
- Migrationsskript: manage.py migrate_paperless_dokumente (DokumentLink → DokumentDatei)
- compose.yml: paperless-Dienst deaktiviert (Legacy-Kommentarblock)
- Migration 0048 angewendet
