Stage every lock before you turn one

Turning off anonymous pulls on the registry a fleet boots from is a change that only fails at the next boot, and a node that can't pull at boot may not come back to tell you. So the flip is split in time: the credential staged inert in every node's config, each node rebooted and proven with a real pull, and the door closed only when the last key has turned.
