Add opt-in low power Sensor dog tracking

Browse Source 
Acquire fresh GPS and validated UTC, check an authenticated owner Companion, and apply saved lost-status cadence with bounded awake windows. Persist request tags, routes, and six-hour flood reservations; preserve the four-day cutoff across sleep and restart.

Keep Dispatcher recovery active after a failed radio wake, honor denied flood retries after lost TxDone, and qualify GPS ownership and clock corrections. Add executable regression tests and nRF52/ESP32 Sensor build jobs.

Validation: six firmware builds, 1829 native test cases, sanitized tracker/storage/GPS/sleep/recovery tests, and strict documentation build. Bluetooth Find My advertising and automatic Room mailbox polling remain separate work.
