[Feature Request]: Support ml-mgie

### Is there an existing issue for this?

- [X] I have searched the existing issues and checked the recent builds/commits

### What would your feature do ?

https://github.com/apple/ml-mgie

### Proposed workflow

Add as an extension that only shows in img2img tab.

### Additional information

_No response_

The issue links Apple's ml-mgie project and requests an extension visible only in the img2img tab. Start by reviewing the linked project and the repository's img2img extension entry points; done would require a working integration that is limited to that tab. No files or tests are named.
