fix(mothership): retry a job dispatch whose usage read failed instead of skipping the run

- a usage outage (`usage_unavailable`) is a failed dispatch attempt, retried and bounded like any other, not a spent limit
- a run skipped for billing records billing's own reason
- the job lane suite closes open connections before stopping its fake worker
