Pull Request Overview

This PR improves the robustness of the conversation title generation feature by adding null/empty handling throughout the entire flow - from the LLM response in the backend to the frontend display.

• Added null-safety check in the backend when LLM returns None or empty response
• Added fallback to null in the frontend service when API returns empty data
• Added fallback to default "New Conversation" title in the UI when title generation fails
