feat: drag-and-drop upload depuis l'ordinateur (fichiers + dossiers récursifs)

Backend:
- POST /api/local-workspace/upload: upload fichiers via multipart, stockage
  disque (/data/uploads/workspace_{id}/), page DB avec content_format='file'
- POST /api/local-workspace/upload-folder: upload récursif de dossiers
  (structure JSON + fichiers), crée l'arborescence complète

Frontend:
- Drop zones sur la page workspace (racine + dossiers ciblés)
- Visual: overlay 'Drop files here', highlight du dossier cible
- webkitGetAsEntry pour walk récursif des dossiers
- Progress bar en bas à droite pendant l'upload
- Auto-reload après upload réussi
- Déduplication automatique des noms de fichiers
