feat(console): unregister inactive revisions

Expose a management DELETE endpoint that refuses to remove an active Deployment, delegates Actor and compiled Component cleanup to Runtime, and removes stored artifacts.

Reconcile Toasty snapshots by deleting absent service and Deployment rows so removed revisions do not reappear after restart.

Persist unregister lifecycle events and verify active-revision protection, artifact deletion, Runtime cleanup, and restart behavior.
