🔴upload_media(target, source_url, data_base64, filename, ttl, ...)
Upload an image or video for a social platform. Returns a public URL that passes the platform media rules, or the problems with fixes. With convert, a fixable file comes back as status "converting": poll get_media until status is "ready" (url set) or "failed". Give the URL to the platform API (image_url / video_url), then call delete_media.
