[Ingest] Persistent crawl run-log + per-source breakdown on admin queue

Each ingestion run now records an IngestionRun row (found/queued/published/flagged/spam/duplicates + a per-source detail string). Admin → صف آگهی‌ها shows a «تاریخچه جمع‌آوری» table of the last 15 runs (hover a row for the per-source breakdown), so admins can see how much each source found vs added over time. IngestionSummary gains TotalFetched. Migration: IngestionRuns table.
