A registration finishing while the purge waited on the run locks wrote
dns_record_id after the purge had already loaded the host, so it skipped the
deletion and then deleted the row holding the only id.

Swallowing it and carrying on deleted the row that held the only reference to
that record, publishing the machine's management address for good. The purge now
fails instead — and is retried, since it re-reads the host and its other steps
are idempotent — so a broken DNS provider becomes a visible failed job rather
than a silent leak.

Codex was right that my never-reuse claim did not hold:
- The lock was released with only a candidate in hand, so two concurrent
onboardings in one datacenter could pick the same name and overwrite each
other's record. The name is now persisted on the host while still locked.
- The number was derived from the hosts that happen to exist, so removing the
highest one handed that number straight back out — a cached name would then
resolve to a different machine. The counter is stored per datacenter, floored
by what is actually in use so a wiped settings store cannot reissue live names.
- PurgeHost deleted the row that carried the record id, leaving the machine's
management address published with nothing left to clean it up.

The FK only nulled host_id, so the adopted peer stayed enabled-but-absent: shown
as "wird angewendet" forever, and re-enabling it would have put the deleted
host's key and address back on the hub. PurgeHost now tombstones that row, which
hands it to the same revocation machinery as everything else.

- ConfigureWireguard checks setup command results and only records the wg_peer
resource after the handshake verifies, so a transient setup failure re-runs
the full setup instead of getting stuck on the idempotent path.
- Host removal now deactivates immediately and queues PurgeHost, which deletes
runs under the runner lock (waiting out a long step) — no 15s LockTimeout error.
