feat: Package 4 Rechtliche Texte — DB-Persistenz fuer Legal Documents, Einwilligungen und Cookie Banner

- Migration 007: compliance_legal_documents, _versions, _approvals (Approval-Workflow)
- Migration 008: compliance_einwilligungen_catalog, _company, _cookies, _consents
- Backend: legal_document_routes.py (11 Endpoints + draft→review→approved→published Workflow)
- Backend: einwilligungen_routes.py (10 Endpoints inkl. Stats, Pagination, Revoke)
- Frontend: /api/admin/consent/[[...path]] Catch-All-Proxy fuer Legal Documents
- Frontend: catalog/consent/cookie-banner routes von In-Memory auf DB-Proxy umgestellt
- Frontend: einwilligungen/page.tsx + cookie-banner/page.tsx laden jetzt via API (kein Mock)
- Tests: 44/44 pass (test_legal_document_routes.py + test_einwilligungen_routes.py)
- Deploy-Scripts: apply_legal_docs_migration.sh + apply_einwilligungen_migration.sh
