_No response_

### What should this feature add?

It would be great if the import model page could show when the models it's found were created and last updated so you could sort by those you've recently added.

Columns could also show the detected model and file type, perhaps even if they're already imported?

### Alternatives

It _might_ be covered by https://github.com/invoke-ai/InvokeAI/issues/4071 perhaps?

### Aditional Content

Something like this kind of layout (obviously not themed like this though! 🤣):
