Fix bot_id: Use bot_id from URL path instead of client message

- Extract bot_name from WebSocket query parameters
- Look up bot_id from bot_name using database
- Pass bot_id to WebSocket message handler
- Use session's bot_id for LLM configuration instead of client-provided bot_id
- Fixes issue where client sends 'default' bot_id when accessing /edu
