fix: Quellenlinks bei String-Nr repariert (574, 610, 611, 617 etc.)

Ursache: Claude liefert teilweise Quellennummern als String statt Integer.
Der Frontend-Vergleich (===) schlug dann fehl: "574" !== 574.

Fixes:
- 95 String-Nummern in Irankonflikt sources_json zu Integer konvertiert
- 5 Duplikate entfernt
- Frontend: Number() statt parseInt/=== fuer robusten Vergleich
- Orchestrator: Automatische Konvertierung von String-Nr zu Integer vor DB-Speicherung
- Cache-Buster aktualisiert
