zjean 54eedf5483 feat(nextcloud): add Nextcloud-compatible API layer
Implement a complete Nextcloud client compatibility layer so that
Nextcloud desktop/mobile sync clients can connect to OxiCloud.

Key additions:
- Login Flow v2 (device auth) with OIDC bridge support
- WebDAV handler compatible with Nextcloud clients (PROPFIND, GET,
  PUT, DELETE, MKCOL, MOVE, COPY, HEAD, PROPPATCH)
- OCS API endpoints (user info, capabilities, notifications stubs,
  sharees, unified search)
- Basic Auth middleware with app password verification, account
  lockout integration, and blake3-keyed auth cache
- App password management: create, list, revoke via both native
  API (JWT-authenticated profile page) and Nextcloud OCS endpoints
- Nextcloud file ID mapping (oc:fileid) with persistent DB storage
- Chunked upload support (Nextcloud v2 chunking protocol)
- Trashbin WebDAV interface
- Avatar (SVG placeholder) and preview (redirect) handlers
- User profile page with app password management UI
- URL user validation on all DAV routes (403 on mismatch)
- Database schema for app_passwords and nextcloud_object_ids tables

All services are behind a `nextcloud.enabled` config flag and
cleanly separated under src/interfaces/nextcloud/.

Dionisio 98fb3e6408 fix(security): VULN-01 admin escalation + VULN-02 path traversal hardening
VULN-01 - Admin privilege escalation:
- Harden register() to reject is_admin=true
- Add /api/setup endpoint with setup_token for initial admin creation
- Add SetupAdminDto and setup_token to AppState
- Remove dead code from auth handler

VULN-02 - Path traversal (CVSS ~8.6):
- Solution A+E: Harden StoragePath constructors (from_string, new, join)
  to strip '..' and '.' segments and reject slash injection
- Solution B: resolve_path() now returns Result<PathBuf>, calls
  validate_path() internally, and verifies resolved path stays under root
- Update StoragePort trait signature to return Result<PathBuf, DomainError>
- Remove dead code: FilePathResolutionPort, StorageVerificationPort,
  DirectoryManagementPort (declared but never implemented)
- Add 17 security tests covering traversal attack vectors

Claude 78c983136f perf: use Arc<str> for repetitive DTO fields to eliminate clone allocations
Replace String with Arc<str> for fields that contain repeated static
values (mime_type, icon_class, icon_special_class, category) in
FileDto, FolderDto, and OptimizedFileContent.

These fields are computed from ~40 static lookup tables and cloned
on every request. With Arc<str>, clone becomes O(1) atomic increment
instead of O(n) heap allocation — saving thousands of allocations/s
under load.

Fields kept as String: id, name, path, folder_id, owner_id
(unique per item, rarely cloned).

Zero API impact — serde serializes Arc<str> identically to String.

Dionisio 81987e9321 fix: URL-decode DAV paths with spaces + feat: app passwords for Basic Auth
Bug fix:
- URL-decode paths in extract_webdav_path(), extract_caldav_path(),
  extract_carddav_path() so folders with spaces (e.g. 'My Folder') no
  longer return 404 when accessed via encoded URIs (%20)
- Properly encode href values in PROPFIND/PROPPATCH/LOCK XML responses
- Decode Destination header in MOVE/COPY operations

New feature - App Passwords (API keys for DAV clients):
- POST /api/auth/app-passwords  → create (shows token once)
- GET  /api/auth/app-passwords  → list (prefix only)
- DELETE /api/auth/app-passwords/:id → revoke
- Auth middleware now accepts both Bearer JWT and Basic Auth
- Argon2 hashed, scoped (webdav/caldav/carddav), optional expiry
- Compatible with DAVx5, Thunderbird, rclone, curl

Tested: 12/12 E2E tests pass (create, list, WebDAV/CalDAV/CardDAV
Basic Auth, URL-decode with spaces, wrong password 401, revoke, post-
revoke 401).

Dionisio 48d853360e feat: implement OAuth 2.0 Device Authorization Grant (RFC 8628) for WebDAV/CalDAV/CardDAV
Adds full Device Authorization Grant flow so DAV clients (rclone, etc.)
can authenticate without browser-based OAuth redirects.

New files:
- Domain entity: DeviceCode with status lifecycle (pending/authorized/denied/expired)
- Port: DeviceCodeStoragePort trait (7 async methods)
- DTOs: request/response types for all device auth endpoints
- Repository: DeviceCodePgRepository (PostgreSQL implementation)
- Service: DeviceAuthService (initiate, verify, approve, deny, poll, cleanup)
- Handler: 6 HTTP endpoints (2 public + 4 protected)
- Static: device-verify.html verification page served at /device

Flow:
1. Client POST /api/auth/device/authorize → device_code + user_code
2. User opens /device?code=XXXX in browser, approves
3. Client polls POST /api/auth/device/token → receives JWT tokens
4. Client uses Bearer token with existing WebDAV/CalDAV/CardDAV middleware

Schema: auth.device_codes table + device_code_status enum added to schema.sql

Closes #152

George Wu 283a80a302 fix: display unlimited quota (∞) when storage_quota_bytes = 0
- Added formatQuotaSize() function to display ∞ for unlimited (0) quota
- Added format_quota_size() Rust function matching JavaScript behavior
- Updated quota defaulting logic from '||' to '== null' check
- This allows 0 (unlimited) to pass through while defaulting to 10 GB
  only when the value is null/undefined
- Call sites now use dedicated formatQuotaSize() or format_quota_size()
  instead of options parameter for cleaner API

Dionisio fb652c07e3 feat(P1+P2): server-authoritative favorites/recent + pre-computed display fields
P1-A: Enrich FavoriteItemDto & RecentItemDto with item_name, item_size,
      item_mime_type, parent_id, modified_at via SQL LEFT JOINs — eliminates
      N+1 per-item fetches.

P1-B: Rewrite favorites.js as server-authoritative (724→380 lines).
      In-memory cache backed by GET /api/favorites; no localStorage.

P1-C: Rewrite recent.js as server-authoritative (341→249 lines).
      GET /api/recent + POST /api/recent/{type}/{id}; no localStorage.

P1 cleanup: Remove dead localStorage cleanup from auth.js logout,
            fix async clearRecentFiles in app.js.

P2: Add icon_class, icon_special_class, category, size_formatted to
    FileDto, FolderDto, FavoriteItemDto, RecentItemDto. New shared
    display_helpers.rs module centralises mime→icon/category/size logic.
    Frontend (ui.js, fileRenderer.js, favorites.js, recent.js) now reads
    pre-computed fields from the API with fallback defaults — eliminates
    5 duplicated mime→icon mapping blocks (~89 lines removed).

Also fixes: synthetic FolderDto in webdav_handler.rs, pre-existing
            missing item_name field in share_service.rs test.

Net: -307 lines across 15 files. cargo check: 0 errors, 0 warnings.
     cargo test display_helpers: 3/3 pass.

- Remove dead handler methods (list_folders_inner, list_folders_for_user, is_user_home_folder, folder_belongs_to_user)
- Add ownership check in get_folder (returns 404 on mismatch)

Batch operations:
- Add trash_service + zip_service to BatchOperationService
- New methods: trash_files, trash_folders, move_folders, download_zip
- New handlers: trash_batch, move_folders_batch, download_batch
- New routes: POST /api/batch/trash, /api/batch/folders/move, /api/batch/download

Frontend:
- Replace findUserHomeFolder (~130 lines) with resolveHomeFolder (~35 lines)
- Remove client-side folder filtering in loadFiles (backend now scopes)
- Rewrite batchDelete: N requests -> 1 POST /api/batch/trash
- Rewrite batchMove: N requests -> 2 POST max (files + folders)
- Rewrite batchDownload: N requests -> 1 POST /api/batch/download (ZIP)
- Search moved to backend, share system uses backend API
- Dark mode fixes, frontend audit improvements

Dionisio 1a1dee9179 fix(oidc): add CSRF state validation, PKCE S256, nonce, secure token delivery, registration guard
Security fixes for OIDC authentication flow:

1. CSRF state validation (High): State nonce is now stored server-side
   and validated on callback (single-use, 600s TTL)

2. PKCE S256 (Medium): code_challenge/code_verifier pair generated per
   RFC 9126, sent in authorize URL and token exchange

3. Nonce in ID token (Medium): Random nonce included in authorize URL,
   verified against ID token claims to prevent token replay

4. Secure token delivery (Medium): Tokens no longer in URL fragments.
   One-time exchange code redirected to frontend, tokens retrieved via
   POST /api/auth/oidc/exchange endpoint (60s TTL, single-use)

5. Registration guard (Low): POST /api/auth/register returns 403 when
   disable_password_login is active in OIDC-only mode

- Hot-reload: OIDC config changes apply without server restart
- Role-based access: admin-only endpoints with 403 for regular users
- Client secret stored securely, never exposed in GET responses
- Env var override detection shown in admin UI
- Clean architecture: repository trait, PG implementation, service, handler
