E2 (B21): аудит + админ-панель пользователей + гео-скоуп

- Модели audit_events (immutable) + audit_changes (field-level old→new);
  Alembic 008_e2_audit.
- backend/audit.py: audit_log() (событие + изменения), audit_retention_days
  (90 дней из security_settings), visible_unit_ids (рекурсивный CTE:
  своё подразделение + подчинённые; РЦУ РЧС/legacy → None = без фильтра),
  can_access_unit, _uuid_hex.
- backend/routers/admin_users.py (manage_users/view_audit):
  GET /admin/users (фильтры status/unit/q, скоуп по подразделению),
  POST (создание с must_change_password, роль, скоуп-проверка),
  PATCH /{id} (роль/юнит/статус/сброс пароля, field-level аудит),
  GET /units (справочник подразделений), GET /audit (ретеншн-фильтр).
  coordinator управляет только своим юнитом+подчинёнными и не трогает РЦУ.
- Грабли SQLite-тестов: UUID колонки хранят hex без дефисов — сравнения
  только в hex-пространстве (_uuid_hex); StaticPool обязателен.
- Тесты E2 (8): создание/блокировка/сброс пароля/скоуп координатора/
  cross-oblast 403/без права 403/аудит user_create.
210 passed, 5 skipped.
