Parent adds guest_activity handling on workspace rename (UPDATE ... SET
workspace_id) and delete (DELETE FROM guest_activity), and reads the deployed
mode under the app-row lock on a rename. The rename/delete queries touch only
workspace_id, leaving the jwt_entry column this PR adds intact. Keep
guest_session_scopes relocated to windmill_api_auth::scopes rather than the
parent's re-added local copy, and sync its refusal message with the parent's.
