Minimal read-only FastAPI surface over the mirrored DB: - GET /api/customers with pagination (page/page_size) and optional channel / owner_account_id / department_id filters, ordered by last_chat_time desc (nulls last) then friend_id. - GET /api/health liveness probe. - Pydantic v2 CustomerOut + generic Page[T] envelope. - CORS configured permissively for the local frontend. - Tests override get_session to an in-memory async SQLite session (StaticPool) and drive the app via httpx ASGITransport.
