fix: Always include current position (FEN) in LLM prompts

- Add FEN and opening data to all user question types (best move, hint, general)
- Prevents LLM from losing track of piece positions during conversation
- Ensures accurate responses based on actual board state
- Fixes issue where tutor would forget piece locations in general questions
