chore(cleanup): toten AI-Copilot-Legacy entfernt — Router nie gemountet, Tabellen von Migration 0137 gedroppt (Chat läuft seitdem über kommunikation/comm_conversations); schemas/OpenAPI-Tag bereinigt; Geister-Test test_ai_copilot.py geloescht (pytest.skip seit Phase 2); test_contacts_lifecycle Route-Anzahl-Failure als Vorbestand bewiesen (83 Routen auch auf clean HEAD)
