fix: hot fixes 23-04-2026 (#856)

* fix(packing): resolve avatar URL path in bag and category assignees (#854)

packingService was returning raw avatar filenames from the DB instead of
the full /uploads/avatars/<filename> path, causing broken profile images
for users with uploaded avatars.

* fix(budget): use Map.get() to fix category rename no-op (#855)

* fix(security): relax Referrer-Policy and document HSTS_INCLUDE_SUBDOMAINS (#862) (#863)

- Change Helmet default from no-referrer to strict-origin-when-cross-origin
  so browsers send the origin on cross-origin requests, allowing Google Maps
  API key restrictions by HTTP referrer to work correctly
- Document HSTS_INCLUDE_SUBDOMAINS in all deployment artifacts:
  .env.example, docker-compose.yml, README.md, unraid-template.xml,
  charts/values.yaml, charts/configmap.yaml, wiki/Environment-Variables.md

* fix(planner): prefetch budget items on trip page mount (#864)

Loads budgetItems alongside reservations when TripPlannerPage mounts so
the Budget category dropdown in ReservationModal and TransportModal shows
pre-existing categories on first open, regardless of whether the Budget
tab has been visited.

Closes #861

* fix(reservations): prevent Invalid Date when end time is set without end date (#866)

When reservation_end_time held a bare time string ("HH:MM"), fmtDate()
produced Invalid Date on the reservation card.

- Modal: when end date is blank but end time is filled, construct a
  same-day ISO datetime using the start date (prevents time-only strings
  from ever being persisted)
- Panel: derive endDatePart via regex so date-only end values ("YYYY-MM-DD")
  still show the multi-day range, while bare time strings are skipped and
  handled correctly by the existing time column logic

Closes #860

* fix(planner): format reservation end time instead of rendering raw ISO string (#867)

Closes #859

* fix(planner): wire Route toggle into mobile day sidebar (#850) (#868)

The per-booking Route icon was missing on mobile because the mobile
DayPlanSidebar invocation in TripPlannerPage didn't pass
visibleConnectionIds or onToggleConnection. Mobile PWA users couldn't
activate reservation map overlays without forcing desktop mode.

Also corrects the Map-Features wiki: fixes the setting name
("Booking route labels" not "Show connection labels"), documents the
route_calculation requirement for travel-time pills, and explains that
overlays are off by default and must be toggled per reservation.
