Добавить статистику и очистку аудита; доработать UI расшифровки.

- Страница /admin/stats: MinIO, pending/consumed, загрузки, audit-метрики
- Кнопка «Очистить» в аудите с подтверждением
- Красивые callout’ы и ошибки пароля; пустой пароль не тратит попытку
- Убрать автоопределение языка; «Расшифруй» в RU UI
