feat: полный бэк и фронт (попытки, разбор, импорт, ИИ, назначения)

- Сервисы: testAttemptService, testAccess, document import/gen/extract, LLM, assignment, aiEditor
- Конфиг: devAuthor, featureFlags; messages/ru; интеграция V.9 (skip без БД)
- API/роуты: app, auth, server; Dockerfile и env example
- Фронт: TestAttempt, TestAttemptReview, AttemptReviewBlock, стили, правки App/api/login/vite
- compose и README; смоук-тесты расширены

Закрывает отсутствие модулей в origin после клона.
