This PR fully implements the Global Chapter-Level Quiz Generation system in the NexusReader application.
### Key Accomplishments:
1. **SubmitQuizResultCommand**: Added MediatR command and handler to persist completed quiz results to the SQLite database securely, using our clean architecture result-pattern.
2. **Dynamic Dashboard Integration**: Re-engineered the user dashboard to fetch, calculate, and display real-time statistics (average score, total books read, total concept nodes mapped, and list of resolved quizzes with their dates and scores) directly from active database queries, eliminating static mockups.
3. **Haptic & Visual Feedback**: Enhanced the quiz flow with interactive CSS transitions, glowing hover feedback, and clear result visualization upon completion.
4. **Robust Verification**: Implemented comprehensive unit tests for `SubmitQuizResultCommandHandler` covering all success and failure/edge cases. Executed full `dotnet test` with 100% success rate.
