Allow for deleting image_upload images in media panel

[karwosts]

Proposed change

Allow frontend uploaded images to be deleted via media panel. Currently there is no way to remove them after they are uploaded.

I do think the manage media UI here is pretty poor user experience (can't actually see the images you are choosing for delete), but we might as well re-use what we already have to be consistent and minimize effort.
