Switch to alembic migrations and pitchfork

Replace calls to `flask db upgrade` with `alembic upgrade head` in SimpleLogin install and update scripts so migrations are executed via Alembic in the virtualenv. For Discourse, remove in-place puma.rb sed tweaks (socket bind and stdout redirect) and update the systemd ExecStart to run `pitchfork -c config/pitchfork.conf.rb` instead of invoking puma directly, using Discourse's recommended process manager.
