feat: DSFA Modul — Backend, Proxy, Frontend-Migration, Tests + Mock-Daten entfernt

- Migration 024: compliance_dsfas + compliance_dsfa_audit_log Tabellen
- dsfa_routes.py: CRUD + stats + audit-log + PATCH status Endpoints
- Proxy: /api/sdk/v1/dsfa/[[...path]] → backend-compliance:8002/api/v1/dsfa
- dsfa/page.tsx: mockDSFAs entfernt → echte API (loadDSFAs, handleCreateDSFA, handleStatusChange, handleDeleteDSFA)
- GeneratorWizard: kontrollierte Inputs + onSubmit-Handler
- reporting/page.tsx: getMockReport() Fallback entfernt → Fehlerstate
- dsr/[requestId]/page.tsx: mockCommunications entfernt → leeres Array (TODO: Backend fehlt)
- 52 neue Tests (680 gesamt, alle grün)
