feat(audit): полноценный writer в audit_log + admin UI (audit + outbox DLQ)

До этого audit_log entity была определена, но никто туда не писал — реальный
аудит шёл только через Hibernate Envers (без user/IP/trace). Теперь:

- AuditLogger service пишет в той же транзакции что и CRUD (DictionaryRecordService).
  Захватывает: user (JWT sub либо preferred_username), scope, IP (X-Forwarded-For),
  UA, trace_id (MDC), request_id. Не ломает основной flow при сбое — только
  громко логирует.
- AuditLogRepository: гибкий search() с nullable фильтрами (dictionary, user,
  action, businessKey, from, to) + Pageable.
- AuditAdminController: GET /admin/audit (paginated) + /admin/audit/export.csv
  (cap 10k строк против OOM).

Frontend:
- /audit route: фильтр-панель, таблица с цветными бейджами (CREATE/UPDATE/CLOSE),
  expand-row с JSON before/after diff, footer IP/UA/req_id, кнопка экспорта CSV.
  Pagination 50/100/200.
- /outbox route: stat-cards pending/DLQ + DLQ-таблица с last_error.
- Nav links + i18n (RU + EN).
