feat(backend/validation): add FluentValidation for DTOs and update controllers
- Add FluentValidation.AspNetCore package
- Create LevelValidators (CreateLevelValidator, UpdateLevelValidator)
- Create LessonValidators (CreateLessonValidator, UpdateLessonValidator)
- Register FluentValidation in Program.cs with auto-validation
- Update LevelsController and LessonsController to use IActionResult
- Make service methods virtual for Moq testing compatibility
- Add 26 integration tests for LevelsController (13 tests)
- Add 34 integration tests for LessonsController (17 tests)
