- Clone: recover via vmExists() when the task ref was lost, instead of
re-cloning the reserved vmid (which Proxmox rejects).
- Deploy: persist the DB password ENCRYPTED before compose up and reuse it on
retry, so a crash can't regenerate a mismatching credential.
- Complete: gate credential delivery on a credentials_sent breadcrumb so a
retry after a crash doesn't re-send the email.
