Persisted save live readiness probe
This probe can read backend contract/schema and optionally run preview-safe validation. It never calls persisted create/update endpoints and never sends admin credentials.
Run the probe with backend on `http://localhost:3000`. If backend is unavailable in this environment, the page should show controlled fail/blocked states.
