Summary

This PR fixes the Project Ideas Generator feature, which was failing to generate project recommendations and displaying generic error messages to users.

The root cause was a combination of frontend and backend issues affecting AI prompt generation, API communication, and response handling. This update restores the complete project generation workflow and improves reliability when interacting with the AI service.
