- 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.

- Stripe webhook fails closed when the signing secret is missing (outside local/testing).
- ReserveResources places + creates the instance under a per-datacenter lock so
concurrent orders can't overcommit a host.
- CloneVirtualMachine reserves the vmid + breadcrumb BEFORE cloning, so a crash
can't mint a new vmid and orphan the first clone.
- CreateCustomerAdmin checks user existence and resets the password instead of
re-running user:add on retry.
