Objekte direkt in Directus speichern + neuer Annotationsworkflow

- DirectusObject Typ + CanvasObject Interface in types.ts
- DrawCanvas nutzt CanvasObject (generisch, nicht mehr ObjectMeta-gebunden)
- Flask: /api/directus/objects (GET/POST), /api/directus/objects/<id> (PATCH/DELETE)
- Flask: /api/directus/setup-m2m (einmalig: m2m für categories/questions)
- api.ts: getDirectusObjects, createDirectusObject, updateDirectusObject, deleteDirectusObject
- DrawIt: Objekte werden in Directus gespeichert (mit picture, bbox/polygon, user_notes, parent)
- DrawIt: Linke Sidebar zeigt Objektliste mit Notizen-Editor und Löschen-Button
- DrawIt: Rechte Sidebar: Modus, user_notes Textarea, Parent-Dropdown, Auswahlen
- Directus: user_notes Feld (textarea), action/resolution/confidence/media versteckt
