feat: unified fleet telemetry — canonical format, GPS/IP geo, WAN health dashboard

- Rewrite telemetry-synology.sh: canonical GL format (modem_0001/wan keys),
  self-contained metrics (no aiwanbal), Eyeride GPS with IP geo fallback
- Add /api/fleet-telemetry to hub: joins tunnel status with fleet Postgres
- Update dashboard.html: per-device WAN health bars, GPS, signal strength
- Fix hub/ingest.sh normalisation: remap old wan1/wan2 → modem_0001/wan
- Bump SPK version: 0.1-0001 → 0.5.0-0001 for GL parity
