feat(pwa): implement real offline mode with IndexedDB sync
...
Add genuine offline read/write capability for trips:
- Dexie IndexedDB schema (trips, places, packing, todo, budget,
reservations, files, mutationQueue, syncMeta, blobCache)
- Repo layer for all domains: offline reads from Dexie, writes
optimistically to Dexie and enqueue mutations for later replay
- Mutation queue with UUID idempotency keys (X-Idempotency-Key),
FIFO flush, temp-ID reconciliation on 2xx, fail-and-continue on 4xx
- Trip sync manager: caches all trips with end_date >= today or null,
auto-evicts 7d after end_date, fetches bundle endpoint in one request
- Map tile prefetcher: bbox from place coords, zooms 10-16, 50MB cap,
warms SW cache via fetch
- Sync triggers: network online → flush + syncAll; WS reconnect →
flush only (rate-limiter safe); visibilitychange/30s → flush only
- WS remoteEventHandler writes through to Dexie on every event
- Server idempotency middleware + idempotency_keys table (migration 100,
24h TTL nightly cleanup)
- GET /api/trips/:id/bundle endpoint for efficient single-request sync
- OfflineBanner component: amber (offline) / blue (syncing) / hidden
- OfflineTab in Settings: cached trip list, re-sync and clear actions
- usePendingMutations hook for per-item pending indicators

fix(tests): mock FormData uploads at API boundary to fix CI timeouts
...
jsdom's FormData is incompatible with undici's ReadableStream serialisation
used by MSW 2.x — requests hang under CI resource constraints but pass locally.
Replace server.use() + implicit HTTP roundtrip with vi.spyOn().mockResolvedValueOnce()
for all five FormData POST tests (uploadAvatar, uploadRestore, addFile, importGpx).
