volker.raschekandCopilot c2f50c4423 fix(ssh)!: refresh public keys after key rotation
Derive public keys on every run and update their files only when the content changes, so existing public keys cannot become stale.

BREAKING CHANGE: The role no longer generates a key pair automatically when root.ssh.private_keys is empty or omitted. Provide private keys explicitly when needed.
