DELETE /themes/{id} removes a pack from the user's library only; the
listing marks those packs removable, and Appearance offers a two-step
delete on them. A bad id is a 400 theme.bad_id (ErrBadID), never a path
in the response. The config is settled before the files go and restored
if they fail, so it never names a pack that is gone.
