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.
