"""File & directory mutation endpoints (ROADMAP #85, tranche 6b).

Handlers déplacés depuis :mod:`backend.main` sans changement de
comportement : mêmes chemins (``PUT/DELETE/PATCH/POST /api/file/*``,
``/api/directory/*``, ``/api/move/*``, ``/api/vault/*/batch-upload``),
mêmes modèles de requête/réponse (déménagés dans :mod:`backend.schemas`),
mêmes dépendances d'authentification et mêmes effets de bord (audit, index
