[Feature Request] Not fully mobile responsive

## Describe the solution you'd like
A responsive layout fix to ensure that the Claude 3 (Haiku) model is fully visible and selectable on mobile devices.

## Why the solution is needed
Currently, the Claude 3 (Haiku) model is not fully displayed on mobile screens, making it difficult for users to select or interact with it. This issue affects the user experience on mobile devices.

## Additional context
This issue was observed when reviewing the app on a mobile device. The model is not completely visible, and there seems to be a layout problem that prevents proper selection.

## Implementation feasibility

- [ ] Yes, I am able to implement the feature and create a pull request.
- [x] No, I am unable to implement the feature, but I am open to discussing the solution.

Start by reproducing the Claude 3 (Haiku) model selector on a mobile device and inspect the responsive layout around the model list. Done means the model is fully visible and can be selected and used on mobile screens.
