[AZ-777] Rewrite spec: real satellite-provider + production C10/C11

Original spec called for direct OSM/CARTO downloads, contradicting
architecture (C11 owns tile network I/O against parent-suite
satellite-provider .NET 8 service; C10 batches descriptors over the
populated C6, never touches the upstream). Rewritten spec drives the
production C10/C11 pipeline against the real satellite-provider
running in docker-compose.test.yml, replacing the mock-suite-sat-
service GET stub. Complexity 5 -> 8 pts (single-ticket override).
Decision log: _docs/_process_leftovers/2026-05-21_az777_complexity_
override.md. Jira AZ-777 description + summary synced. Autodev state
pauses for next session to pick up Phase 1 (satellite-provider
stand-up + smoke test).
