feat: 6 Dokumentations-Module auf 100% — VVT Backend, Filter, PDF-Export

Phase 1 — VVT Backend (localStorage → API):
- migrations/006_vvt.sql: Neue Tabellen (vvt_organization, vvt_activities, vvt_audit_log)
- compliance/db/vvt_models.py: SQLAlchemy-Models für alle VVT-Tabellen
- compliance/api/vvt_routes.py: Vollständiger CRUD-Router (10 Endpoints)
- compliance/api/__init__.py: VVT-Router registriert
- compliance/api/schemas.py: VVT Pydantic-Schemas ergänzt
- app/(sdk)/sdk/vvt/page.tsx: API-Client + camelCase↔snake_case Mapping,
  localStorage durch persistente DB-Calls ersetzt (POST/PUT/DELETE/GET)
- tests/test_vvt_routes.py: 18 Tests (alle grün)

Phase 3 — Document Generator PDF-Export:
- document-generator/page.tsx: "Als PDF exportieren"-Button funktioniert jetzt
  via window.print() + Print-Window mit korrektem HTML
- Fallback-Banner wenn Template-Service (breakpilot-core) nicht erreichbar

Phase 4 — Source Policy erweiterte Filter:
- SourcesTab.tsx: source_type-Filter (Rechtlich / Leitlinien / Vorlagen / etc.)
- PIIRulesTab.tsx: category-Filter (E-Mail / Telefon / IBAN / etc.)
- source_policy_router.py: Backend-Endpoints unterstützen jetzt source_type
  und category als Query-Parameter
- requirements.txt: reportlab==4.2.5 ergänzt (fehlende Audit-PDF-Dependency)

Phase 2 — Training (Migration-Skripte):
- scripts/apply_training_migrations.sh: SSH-Skript für Mac Mini
- scripts/apply_vvt_migration.sh: Vollständiges Deploy-Skript für VVT
