fix(journey): fix issue #704 — active logic, archive, places rename, search, trip reminders

- Derive journey lifecycle from linked trip dates (live/upcoming/completed/draft)
  instead of relying solely on status field; status=archived always wins
- Add Archive/Restore Journey action in journey settings dialog
- Rename cities → places end-to-end (SQL alias, TS types, stats field, all locales)
- Wire up search icon: toggles inline input, filters by title+subtitle client-side
- Fix channelConfigured check: trip reminders enabled by default since inapp is
  always available; remove channel check, controlled solely by admin setting
- Expose notify_trip_reminder toggle in Admin → Settings → Notifications
- Add trip_date_min/trip_date_max to listJourneys SQL for client-side lifecycle
- Add archived status to Journey type (server + client)
- Update all 15 locale files with new keys (search, archive, places, trip reminders)
