- Dedicated 'provisioning' queue connection (retry_after 2400) + worker
(--timeout=2100); AdvanceRunJob tries=1, timeout=2100 on that queue.
- Run lock TTL raised to 2100s so a long step can't be run concurrently by a
duplicate tick-dispatched job.
- StartHostOnboarding creates host+run in a transaction, dispatches after commit.
