Quellenverwaltung: Boulevard-Kategorie, Duplikat-Prüfung, Domain-Normalisierung

- Boulevard als Kategorie in HTML-Dropdowns, JS-Labels und Pydantic-Validierung
- create_source: URL-Duplikat-Prüfung (409 Conflict bei existierender URL)
- create_source + update_source: Domain via _DOMAIN_ALIASES normalisieren
- System-Quellen (auto-entdeckt) sind jetzt von allen Nutzern editierbar
