feat: odometer in trips/overview, trips upload toggle, fix video count

- OBD odometer now logged to tracking rows on every GPS snapshot
- trips table: START_ODOMETER/END_ODOMETER columns (migration)
- build_trip_summaries: picks odometer from first/last tracking row
- list_trips: uses real OBD odo, falls back to cumulative distance
- overview stats: odometer_km (max seen from OBD), video_count fixed
- history page: Odometer column shows start→end km per trip
- app_upload: TRIPS_UPLOAD_SETTING_KEY, is_trips_upload_enabled()
- _upload_tracking_batch: skips when trips upload is off
- settings: separate 'Upload trips & GPS' toggle from dashcam toggle
