IDownloadProcessingJobService.CleanupOldJobsAsync existed but had no caller, so the DownloadProcessingJobs table grew unbounded on long-running instances. Every queue-snapshot reconciliation queries this table (pending/all job download IDs for completed DDL items), so the backlog also added steady per-snapshot cost. Add DownloadProcessingJobCleanupService, a hosted BackgroundService that purges terminal (Completed/Failed) jobs older than a 7-day retention window shortly after startup and then daily. Retention is a constant to keep this change migration-free; making it configurable is a follow-up. Tests: terminal jobs past retention are removed while recent and non-terminal jobs are retained; no-op when nothing is eligible; service is registered as a hosted service.

Addresses the 3a (job retention) portion of #640.

Does not touch the 3b (orphan terminalization) part of #640 — that's a separate, more behavioral change and is left for discussion on the issue.
