Hannah Wolfe c5eda57f1e Minor internal apps improvements
refs #6589

- add internalAppsPath as a proper config path
- middleware/routes will be setup for any internal apps which have the function
- this should be refactored into some sort of proper hooks system as part of apps
- internal apps get permission to do anything the proxy allows
