refactor(klassifikation): Klassifikation aus Monitor entfernt — Pflege jetzt in der Verwaltung

Endpoints unter /api/sources/classification/* weg, Service-Module (source_classifier, external_reputation) gelöscht. Quellen-Modal verliert Tab Klassifikations-Review, Klassifikations-Section in der Edit-Form, alle Bulk-Buttons (Sync, Klassifikation starten, Bulk-Approve). API-Methoden in api.js entfernt, alignment-Helper raus, saveSource entschlackt.

Read-Only bleibt: Filter-Dropdowns über der Quellenliste (Politik, Medientyp, Reliability, Externe Reputation, Alignment) und Inline-Badges (_renderClassificationBadges + Label-Maps in components.js). Kunde sieht nur freigegebene Werte.

GET /api/sources liefert weiter Klassifikations-Felder + alignments für die Anzeige; SourceCreate/SourceUpdate akzeptieren keine Klassifikations-Felder mehr.

Bulk-Klassifikations-Skripte entfernt — Pflege läuft über Verwaltungs-UI.
