Add sorting by file size to viewing local models

You can close this if it is not a good idea. I think it would be convenient.

I agree, but i have no idea how the UI stuff works 😅

I can look into it in a couple of days.

@JNeuvonen I think it'd be great to have! We can either sort by rust backend (when we return the model, we add a custom sort middleware) or just as an UI layer on the frontend. I think the first would be faster, the 2nd would shuffle the UI a bit on load :d...

We can cache the sort persistency via the backend config state as well
