[Enhancement]: Make prompt-to-code window resizable

### Before Requesting

- [X] I have searched the existing issues, and there is no existing issue for my feature request

### What feature do you want?

Hi, great app. My only suggestion is the following:

The promt-to-code window should be resizable the same way as the chat window. It seems like the width is fixed.

Alternative solution options would be

- Being able to reduce the font size (There is a setting in the "Feature" section, but it is greyed out).
- Disable text wrapping for this window.
