Initial commit: adacam-api v1.0.0

Clean Python Flask replacement for odc-api (434k lines Node.js → ~350 lines Python)
- GET /api/1/landmarks/last/{N} - last N detections from SQLite
- POST /api/1/landmarks - ingest detections + forward to AdaMaps
- GET /api/1/gnssConcise/latestValid - GPS fix from Redis
- GET /api/1/status - device status
- GET /api/1/deviceinfo - device identity
- GET /api/1/recording/frames/latest - latest frame path

No /api/1/cmd - that's the CVE, it's gone.

Includes:
- SQLite for local storage + offline queue
- Background thread for AdaMaps retry
- systemd service unit
- install.sh for device deployment
