feat(chat): add auto title generation, inline renaming, and styled delete modal

- Fix missing conversationsStore import for auto title generation
- Make model ID dynamic in generateTitle() with error handling and fallback
- Add inline editing for manual conversation renaming in sidebar
- Add updateConversationTitle API endpoint and store method
- Replace browser confirm() with styled ConfirmationModal for delete
- Update Modal and ConfirmationModal with glassmorphism styling
- Add DEV_BYPASS_AUTH and GOOGLE_GENAI_API_KEY to env generation
