general cleanup. Removed unnecessary files.

didn’t need message logic in sender. remove top level manifest and
deployment artifacts, now we’re doing separate pushes.

if MYSQL_URL fails, fall back to DATABASE_URL. TODO: maybe this should
be the other way.

so we can push them separately. Also there were errors trying to do a
unified push.
there were some merge errors here
made the table sort by descending date
