[AZ-777] Phase 1 hotfix (z/x/y) + Phase 2 Derkachi seed + ops

Phase 1 hotfix:
- C11 HttpTileDownloader adapted to satellite-provider v2.0.0
  z/x/y inventory contract (bulk POST keyed by slippy-map coords).
- Unit tests rewritten to exercise the new inventory schema.
- E2E smoke test updated to match the v2.0.0 wire.

Phase 2 (Derkachi seed + smoke-validated on Jetson):
- tests/fixtures/derkachi_c6/{README,bbox.yaml,seed_region.py}
  drives POST /api/satellite/region against satellite-provider
  with Google Maps as the imagery source. Smoke run produced
  4 regions, 175 tiles, inventory 32/32.
- scripts/mint_dev_jwt.py + run-tests-jetson.sh auto-mint and
  export SATELLITE_PROVIDER_API_KEY using JWT_SECRET / JWT_ISSUER
  / JWT_AUDIENCE env vars (no host port mappings; e2e-runner
  reaches SP via internal docker network only).

Spec amendment: AZ-777 todo spec updated to record the
Google Maps imagery source decision and STOP-gate state.

AZ-777 Phase 3+ work is superseded by Epic AZ-835 (see next
commit).
