m b36247dfb9 feat: append-only audit trail for all mutations (P0)
- Database: kanzlai.audit_log table with RLS, append-only policies
  (no UPDATE/DELETE), indexes for entity, user, and time queries
- Backend: AuditService.Log() with context-based tenant/user/IP/UA
  extraction, wired into all 7 services (case, deadline, appointment,
  document, note, party, tenant)
- API: GET /api/audit-log with entity_type, entity_id, user_id,
  from/to date, and pagination filters
- Frontend: Protokoll tab on case detail page with chronological
  audit entries, diff preview, and pagination

Required by § 50 BRAO and DSGVO Art. 5(2).
