- Fix SEC-005: rewrite path traversal test to upload a real file, inject
  traversal filename into DB, and assert the download does not succeed
- Fix SEC-007: rename misleading test description to reflect it tests
  rejection of an invalid token, not acceptance of a valid one
- Delete health.test.ts: all 3 tests were exact duplicates of auth.test.ts
  and misc.test.ts
- Remove duplicate describe blocks from misc.test.ts: Categories endpoint
  (duplicate of categories.test.ts) and App config (duplicate of auth.test.ts)
- Remove TRIP-016 from trips.test.ts: weaker duplicate of TRIP-007 (no body
  assertion)
- Remove API Keys describe block from profile.test.ts: canonical copy lives
  in security.test.ts where it belongs
- Remove avatarUrl describe block from budgetService.test.ts: identical tests
  already exist in authService.test.ts; drop now-unused import
- Add DB verification to ASSIGN-007 and PACK-006 reorder tests: query
  day_assignments / packing_items after PUT reorder to confirm order changed
- Strengthen BUDGET-007/008/009: add member/payer setup and assert concrete
  values (total_paid, per-user balance, flow direction and amount)
- Remove 6 pointless Map-semantics tests from inAppNotificationActions.test.ts;
  keep only the two built-in registration checks
- Remove 5 passthrough tests from queryHelpers.test.ts; keep the 4 tests that
  cover actual flat-to-nested transformation logic

Subject: [PATCH 2/6] test: expand test suite to 87.3% backend coverage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add new integration test files covering previously untested routes:
- categories.test.ts — GET /api/categories
- oidc.test.ts — full OIDC login flow (callback, state, errors)
- settings.test.ts — GET/PUT /api/settings, bulk save
- tags.test.ts — CRUD for trip tags
- todo.test.ts — todo items CRUD and reorder

Add new unit test files covering service-layer logic:
- adminService.test.ts — user/invite management, packing templates, OIDC settings
- atlasService.test.ts — atlas search and place enrichment
- authServiceDb.test.ts — DB-backed auth helpers (login, register, MFA)
- backupService.test.ts — export/import/restore logic
- categoryService.test.ts — category CRUD
- dayService.test.ts — day management and accommodation helpers
- mapsService.test.ts — route/directions helpers
- oidcService.test.ts — OIDC state, auth code, role resolution, user upsert
- packingService.test.ts — packing item/bag/template operations
- placeService.test.ts — place CRUD and tag attachment
- settingsService.test.ts — settings get/set/bulk
- tagService.test.ts — tag CRUD
- todoService.test.ts — todo CRUD and reorder
- tripService.test.ts — trip CRUD, member management, archiving
- vacayService.test.ts — vacay integration helpers
- tripAccess.test.ts (middleware) — requireTripAccess middleware

Expand existing integration and unit test files with additional cases
across admin, atlas, auth, backup, collab, days, files, maps, memories
(Immich/Synology), notifications, places, reservations, share, vacay,
weather, auth middleware, ephemeral tokens, notification preferences,
permissions, SSRF guard, and WebSocket connection tests.

Update test helpers (factories.ts, test-db.ts) with new factory
functions and seed data required by the expanded suite.

Fix minor issues in server/src/routes/reservations.ts and
server/src/services/atlasService.ts surfaced by new test coverage.

Update sonar-project.properties to reflect new coverage thresholds.

Subject: [PATCH 3/6] test: relax ReDoS timing thresholds for CI compatibility
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MAPS-024 and MAPS-026 were asserting < 100ms on adversarial regex input,
which passed locally but flaked on CI runners (~150-170ms). These are not
cases of catastrophic backtracking — true ReDoS would take seconds, not
~150ms. Raise the threshold to 500ms to remain meaningful while being
reliable across environments.

Subject: [PATCH 5/6] fix(oidc): resolve login/logout loop in OIDC-only mode

Three distinct bugs caused infinite OIDC redirect loops:

1. After logout, navigating to /login with no signal to suppress the
   auto-redirect caused the login page to immediately re-trigger the
   OIDC flow. Fixed by passing `{ state: { noRedirect: true } }` via
   React Router's navigation state (not URL params, which were fragile
   due to async cleanup timing) from all logout call sites.

2. On the OIDC callback page (/login?oidc_code=...), App.tsx's
   mount-level loadUser() fired concurrently with the LoginPage's
   exchange fetch. The App-level call had no cookie yet and got a 401,
   which (if it resolved after the successful exchange loadUser()) would
   overwrite isAuthenticated back to false. Fixed by skipping loadUser()
   in App.tsx when the initial path is /login.

3. React 18 StrictMode double-invokes useEffect. The first run called
   window.history.replaceState to clean the oidc_code from the URL
   before starting the async exchange, so the second run saw no
   oidc_code and fell through to the getAppConfig auto-redirect, firing
   window.location.href = '/api/auth/oidc/login' before the exchange
   could complete. Fixed by adding a useRef guard to prevent
   double-execution and moving replaceState into the fetch callbacks so
   the URL is only cleaned after the exchange resolves.

Also adds login.oidcLoggedOut translation key in all 14 languages to
show "You have been logged out" instead of the generic OIDC-only
message when landing on /login after an intentional logout.

Closes #491
