Bug fixes - April 27th 2026 (#907)

* fix: clean up dangling FK references before deleting a user

Resolves FOREIGN KEY constraint failed (500) on DELETE /api/admin/users/:id
and DELETE /api/auth/me when the target user had rows in trip_members.invited_by,
share_tokens.created_by, budget_items.paid_by_user_id, journeys.user_id,
journey_entries.author_id, journey_contributors.user_id, or
journey_share_tokens.created_by — none of which had ON DELETE clauses.

Introduces deleteUserCompletely() in userCleanupService.ts which wraps all
cleanup and the final DELETE FROM users in a single transaction. Both
adminService.deleteUser and authService.deleteAccount now call it instead of
the bare DELETE. Tests ADMIN-005b and AUTH-040 cover all reference types
including notification sender/recipient and notice dismissals.

* test: extend FK deletion tests to cover journeys, files, and photos

ADMIN-005b and AUTH-040 now also seed and assert:
- owned journey with entries (cascade-deleted via journeys.user_id cleanup)
- trip_files.uploaded_by (SET NULL — file survives, attribution cleared)
- trek_photos.owner_id (SET NULL — photo record survives, owner cleared)
- trip_photos.user_id (CASCADE — photo association removed)

* test: extend user deletion tests to cover all FK relationships

ADMIN-005b and AUTH-040 now seed and assert every user FK relationship:

CASCADE (row deleted): trips, trip_members, tags, mcp_tokens, oauth_tokens,
oauth_consents, vacay_plans, vacay_plan_members, bucket_list,
visited_countries, visited_regions, packing_templates, invite_tokens,
collab_notes, settings, password_reset_tokens, notification_channel_preferences

SET NULL (row survives, column nulled): categories, todo_items.assigned_user_id,
packing_bags, audit_log

Caught and fixed: notification_preferences was dropped in migration 72;
correct table is notification_channel_preferences.

* fix: preserve URL hash and OIDC redirect target through login flow

- Include location.hash in redirect param at all three producer sites
  (ProtectedRoute, axios 401 interceptor, OAuthAuthorizePage) so
  hash fragments survive the login bounce
- Stash redirectTarget in sessionStorage before any OIDC provider
  redirect and restore it after the code exchange, since the IdP
  strips the original ?redirect= param during the roundtrip
- Clear sessionStorage on OIDC error to avoid stale state
- Add tests covering sessionStorage stash on mount, navigate to saved
  redirect after OIDC exchange, fallback to /dashboard, and cleanup
  on error

* fix: use day position instead of ID for accommodation date range clamping

Math.min/Math.max over raw day IDs breaks the start/end picker when a
trip's day IDs are non-monotonic relative to day_number (normal after
repeated generateDays extend/shrink cycles). Replaced with findIndex
lookups so clamping is always based on positional order.

Closes #889

* fix: normalize env var comparisons to be case-insensitive

All NODE_ENV, DEMO_MODE, OIDC_ONLY, FORCE_HTTPS, COOKIE_SECURE, and
ALLOW_INTERNAL_NETWORK checks now use .toLowerCase() so values like
'Production' or 'True' behave identically to their lowercase forms.
Also adds APP_VERSION to the startup banner.

* fix: delete surplus days when shortening a trip

When shrinking a trip's date range, surplus days are now deleted along
with their assignments, notes, and accommodations (cascade). Places
remain in the trip pool; reservations keep their day reference nulled
by the existing ON DELETE SET NULL constraint (issue #909).

Updates TRIP-SVC-011 to reflect the new behaviour; adds TRIP-SVC-016
as a regression test for the empty-day case.

* fix: auto-backup retention deletes itself and manual backups on Docker

Two bugs in cleanupOldBackups:
1. Filter was .endsWith('.zip') — swept manual backup-*.zip files too.
   Now restricted to auto-backup-* prefix.
2. Age was derived from stat.birthtimeMs, which is 0 on overlayfs
   (Docker default), making every backup appear epoch-old and get
   deleted immediately. Age is now parsed from the filename timestamp
   and falls back to mtimeMs (reliable on overlayfs).

Also converts inline require('./services/auditLog') calls to a static
import throughout scheduler.ts, and adds 8 unit tests covering the
fixed retention logic including the overlayfs regression case.

* test: update TRIP-024 to match delete behavior on trip shrink

* feat: add bypass-branch-check label to skip branch enforcement
