App 2.3.0: Server tab, live telemetry to the car server

- New Server tab: server URL, ingest token and installation id, with
  Save, Test connection (health, then a read-only token check) and the
  config-file import that upstream removed (app folder / USB stick first,
  document picker as fallback). Settings are kept encrypted and read on
  every use, so the service picks up a change without a restart. Each
  installation generates its own id; the inherited upstream UUID and
  the baked-in CONSUMPTION_API_* build fields are gone.
- Live telemetry restored from before ea8032a (TelemetryPayload,
  UploadCadence, UploadSettings, GPS) and sent in batches to
  POST /v1/telemetry instead of ABRP; the server forwards to ABRP. Adds
  ext_temp, voltage and current. Unsent samples queue in memory (about
  8 h) while offline.
- Upload tab: the live-telemetry switch and cadence controls work again;
  the dead service and autostart switches are removed.
- Manifest: location permissions and foreground service types.
- Unit tests compile again: 114 (stable) / 136 (unstable) pass. Tests
  for the deleted AbrpApi and HeadUnitWeather removed; new tests for
  ServerConfig and TelemetryQueue. Lint passes.

Not yet tried on the car.
