## Summary by CodeRabbit

- **New Features**
  - Improved AI panel behavior with explicit modes for input and answer generation, providing a more intuitive user experience when interacting with AI features.

- **Refactor**
  - Streamlined AI panel toggling logic for more consistent and predictable panel states during different actions.

- **Tests**
  - Enhanced AI image generation test to simulate user input and send actions for more accurate end-to-end validation.
