Allow assets to be named upon upload & show S3 link after upload is complete

[bcardarella]

Currently there is no way to name an asset other than taking the original filename. We should have a way to do this but before the asset is processed into thumbnail sizes and fingerprinted.

After the upload is complete we should display the S3 and Repo links like we do when viewing the asset after upload

I realize the upload will result in multiple files. So the result modal should should the S3 and Repo links for each individual resize type.

Something like this mockup:

Linking the figma design here for reference https://www.figma.com/design/k8NhxbRRb8hm4fc1RQHms1/Media-Library
On that design we have a similar screen when you can see the variants with a copy button, similar to your mockup.
