Reliable background job delivery

### Fixed
- Release expired database connections after worker jobs and each reaper work unit.
- Retain job recovery evidence during temporary database failures or uncertain Redis queue writes.
- Prevent stale reaper cleanup from deleting a newer worker claim.
### Upgrade notes
- Restart job workers after upgrading.
