Daemons - add status of environment to daemon console, etc

Summary: Shows the UI everywhere. Also asort() the keys before calculating the environment hash as that is probably an issue for someone at some point we just don't need to have. Ref T5968.

Test Plan: Viewed the setup check and saw a link to the daemon console. Viewed the daemon console and saw the various stale config daemons. Clicked a daemon and saw a "stale config" header icon where expected. Restarted daemons and all of this went away.
