Phase 6: Verwendungs-Sicht pro Grundquelle

Backend
- /api/sources/global liefert pro Quelle articles_7d, articles_30d und
  tenant_excluded_count (eine aggregierte Query mit CTEs, kein N+1).
- Match-Logik fuer Articles: LOWER(articles.source) = LOWER(sources.name)
  - articles.source_url ist Artikel-URL, NICHT Feed-URL, daher matcht das
    nicht mit sources.url. source-Name-Match liefert sinnvolle Treffer.
- tenant_excluded_count zaehlt distinct organization_ids aus
  user_excluded_domains (per LOWER(domain)-Match).

Frontend
- dashboard.html: zwei neue sortierbare Spalten Aktivitaet (7d/30d) +
  Sperren in der Grundquellen-Tabelle.
- style.css: .activity-cell + .exclude-badge Styles (mit zero-Variante
  fuer ruhigen Look bei keiner Aktivitaet/Sperre).
- sources.js:
  - cols 9 -> 11
  - Render: 7d-Wert fett, 30d-Wert dezent, Tooltip 7 Tage / 30 Tage
  - Sort-Logik: NUMERIC_FIELDS um articles_7d/articles_30d/tenant_excluded_count
    erweitert (numerischer Compare statt localeCompare)
