Upload covers via copy/paste

[RayBB]

Proposal

We would like to be able to upload covers via copy/paste.
Also drag/drop would be nice.
We can no longer support uploading via remote URLs for security purposes.

Justification

The problem is now people have to download and then upload covers which creates friction.

This would make things easier to upload.

I know our current upload system is in an old iframe and a little hard to develop with (in my opinion)

FWIW, MusicBrainz/Cover Art Archive (another IA project) has a long-standing ticket for URL uploading: https://tickets.metabrainz.org/browse/MBS-4641

And there’s a community developed userscript to achieve this functionality: https://github.com/ROpdebee/mb-userscripts/tree/main?tab=readme-ov-file#mb-enhanced-cover-art-uploads (Ray asked me elsewhere to show a demonstration of the userscript in action, but due to the attack(s) on IA, cover art uploading and editing is currently disabled on MB.)
