refactor: simplify GPS page, lean into Traccar for live map and trips

Remove ~2,300 lines of code that duplicated Traccar's native capabilities:
- Remove Leaflet live map, trip stats/playback, and OSRM route matching from frontend
- Delete osrm.service.ts entirely (415 lines)
- Remove 6 dead backend endpoints and unused service methods
- Clean up unused hooks and TypeScript types
- Keep device enrollment, QR codes, settings, and CommandCenter integration
