Add door_code_changed to GuestStateDiff so lock slot updates on in-window code changes

Previously a door code change fetched from the backend was stored silently with
no re-push to the lock. door_code_changed mirrors wifi_key_changed and triggers
_async_run_check_in_actions, so the periodic sync picks up admin-initiated code
rotations automatically.
