feat(backend/application): Complete Lesson Management feature implementation

Browse source 
- Integrated Quiz completion with ProgressService: when a quiz is passed (>=80%), the associated lesson is automatically marked as completed
- Created LessonUnlockService for centralized lesson unlocking business logic
- Created LevelCompletionCalculator for calculating level completion metrics
- Registered new services in Program.cs DI container
- Updated QuizQuestionService to include ProgressService dependency
- Updated documentation (ROADMAP.md, lesson-management.md) to reflect completion
- Fixed QuizQuestionServiceTests to work with updated dependencies

All tests pass (296 total: 148 unit + 148 integration).
