Modernize Audit

Summary: Adds mobile support to Audit, converts tables to object item views. I also colored 'concerns' and 'audit required' in the list, but nothing else. We can add more if needed but I'm assuming these are the two most important cases.

Test Plan: Tested as much as I could, a little unsure of a few things since my local repo isn't super filled. Will let epriestley run through.
