feat(admin-ui): поиск справочников + счётчик активных записей

Backend:
- DictionaryRecordRepository.countActiveGroupedByDictionary — один GROUP BY
  по всем справочникам с фильтром по scope, без N+1.
- DictionaryResponse.recordCount (nullable) + factory from(d, count).
- DictionaryDefinitionController передаёт счётчики в list/get,
  фильтрованные по currentScopes() пользователя.

Frontend:
- SearchInput над сеткой карточек, client-side filter по
  name/displayName/description (case-insensitive, useDeferredValue).
- Badge "N записей" (i18n plural ru/en) в углу карточки.
- "Показано N из M" рядом с поиском.
- EmptyState когда поиск пустой.
