PUT /api/v1/media/:id on a picture already posted changed the upload but never the post, which keeps its own copy, so
the new description or focal point reached nobody. As on Mastodon, PUT now takes only media not posted yet (404
otherwise), and a status edit takes media_attributes[] (id, description, focus; from a JSON body or a form): the
uploads and the post's copies change, and the Update the edit federates carries them. An edit that sends no media
keeps them as they were described. No pasture scenario edits a description, so the sweep could not see this.
MediaLifecycleTests: PUT on a posted picture is refused, an edit describes it again and keeps its warning, flag and
language as sent.
