Upload a custom YouTube video thumbnail

Upload a custom thumbnail for a YouTube video post. The image is stored as Publora-tracked media and a mediaId + url are returned; attach them via platformSettings.youtube.thumbnail on update-post. A thumbnail cannot be set on create-post — the upload requires an existing postGroupId (draft or scheduled) that is not currently publishing. JPEG or PNG, 2 MB max, minimum 640x360 px (1280x720 recommended).
