feat: integrate AI features for question generation and tutoring
- Added AI routes for generating questions, providing hints, and tutor chat functionality. - Implemented AI client setup and model retrieval in aiClient.ts. - Created aiAssist.ts for handling AI-related operations including question generation and hint retrieval. - Updated services to utilize the new AI client and assist functions. - Enhanced frontend components to support AI question generation and tutor chat, including UI for generating questions and displaying hints. - Added localization strings for new AI features in English and Dutch. - Updated exam review process to include AI-generated hints and tutor chat functionality.
