Fixes issue #959 — two bugs causing ChatGPT's custom MCP connector to fail:
1. RFC 9728 path-based PRM: ChatGPT requests
/.well-known/oauth-protected-resource/mcp (path-aware URL per RFC 9728
§5). The old TREK handler only registered the base path; requests for
the path variant fell through to the SPA catch-all and returned HTML.
mcpAuthMetadataRouter registers the path-aware URL automatically.
2. DCR without scope: ChatGPT never sends scope during Dynamic Client
Registration (RFC 7591 makes it optional). The old handler returned
400 for missing scope. clientRegistrationHandler accepts it;
trekClientsStore.registerClient defaults to ALL_SCOPES when absent,
and the user still grants only what they approve at the consent UI
(scopeSelectable=true for DCR clients is unchanged).
Hybrid approach: SDK handles /.well-known, /oauth/authorize (redirect to
consent SPA), and /oauth/register. TREK keeps its own /oauth/token and
/oauth/revoke because SDK clientAuth does plain-text secret comparison
while TREK uses SHA-256 hashing — incompatible without a full clientAuth
rewrite.
SPA consent page renamed /oauth/authorize → /oauth/consent to avoid
routing conflict with the SDK's backend authorize handler now mounted at
that path. Existing URL paths (/oauth/token etc.) are unchanged so
active Claude.ai connections are unaffected.
Other: lazy-init SDK metadata router so getAppUrl() (DB query) is not
called at createApp() time; path-aware mcpAddonGate so only /.well-known
returns 404 when MCP is disabled (previously a blanket middleware blocked
all routes including static files); /api/oauth mounted before the SDK
middleware chain so SPA-facing routes with their own 403 gates are
reached correctly.
The polyfill was injected as an inline script at build time, causing a hard
CSP block under script-src 'self'. All browsers that support ES modules also
support modulepreload natively, so the polyfill is unnecessary.
- Exclude sensitive API paths (auth, admin, backup, settings) from SW cache
- Restrict upload caching to public assets only (covers, avatars)
- Remove opaque response caching (status 0) for API and uploads
- Clear service worker caches on logout
- Only logout on 401 errors, not transient network failures
- Fix register() TypeScript interface to include invite_token parameter
- Remove unused RegisterPage and DemoBanner imports
- Disable source maps in production build
- Add SRI hash for Leaflet CSS CDN

Real-Time Collaboration (WebSocket):
- WebSocket server with JWT auth and trip-based rooms
- Live sync for all CRUD operations (places, assignments, days, notes, budget, packing, reservations, files)
- Socket-based exclusion to prevent duplicate updates
- Auto-reconnect with exponential backoff
- Assignment move sync between days
Performance:
- 16 database indexes on all foreign key columns
- N+1 query fix in places, assignments and days endpoints
- Marker clustering (react-leaflet-cluster) with configurable radius
- List virtualization (react-window) for places sidebar
- useMemo for filtered places
- SQLite WAL mode + busy_timeout for concurrent writes
- Weather API: server-side cache (1h forecast, 15min current) + client sessionStorage
- Google Places photos: persisted to DB after first fetch
- Google Details: 3-tier cache (memory → sessionStorage → API)
Security:
- CORS auto-configuration (production: same-origin, dev: open)
- API keys removed from /auth/me response
- Admin-only endpoint for reading API keys
- Path traversal prevention in cover image deletion
- JWT secret persisted to file (survives restarts)
- Avatar upload file extension whitelist
- API key fallback: normal users use admin's key without exposure
- Case-insensitive email login
Dark Mode:
- Fixed hardcoded colors across PackingList, Budget, ReservationModal, ReservationsPanel
- Mobile map buttons and sidebar sheets respect dark mode
- Cluster markers always dark
UI/UX:
- Redesigned login page with animated planes, stars and feature cards
- Admin: create user functionality with CustomSelect
- Mobile: day-picker popup for assigning places to days
- Mobile: touch-friendly reorder buttons (32px targets)
- Mobile: responsive text (shorter labels on small screens)
- Packing list: index-based category colors
- i18n: translated date picker placeholder, fixed German labels
- Default map tile: CartoDB Light
