//! Integration tests for the admin crawler observability/control API.
//!
//! The default test harness wires `AppState.crawler = None` (no daemon),
//! so the *control* endpoints return 503 and the *read* endpoints that
//! work off the DB (status shell, dead-jobs list/requeue) still function.
//! This is exactly the production "daemon disabled" posture.
