Remove: mask units so Restart=always cannot respawn
- Panel remove now disable+mask+SIGTERM --kill-who=all before ACK. Restart=always / watchdog cannot bring leaf agents or the node back.
- TON: oneshot RemainAfterExit (ton-<env>.service) is not 'still running'. Truth is validator-engine / mytoncore. Stock validator.service is masked, not deleted.
