feat: CAM-based use case detection engine, decouple DENM from sensor triggers

Browse Source 
Added:
- UseCaseDetectionEngine: IMA-B, IMA-S, RTW-B, LTW-B, SMVA/BCW-B via per-station
  CAM history, yaw-rate/heading-trend turn detection, Info/Awareness/Warning alerts
- Ego state from obu_gnss (~4Hz, yaw rate) with phone GPS fallback when stale
- Human-readable alert narratives + technical detail in V2X Monitor
- Settings > Use Case Alerts per-use-case toggles

Fixed:
- DENM no longer auto-fires on braking/stopping; manual-only (antenna/RSU test)
- Removed unwired CamBuilder.kt (dead code, contradicted CAM-only architecture)
- TripRecordingService no longer depends on MQTT/OBU connectivity
