CSS Tweaks to reviewers status list

Summary: Updates the review status list to align better inside property lists. Alsu uses the default colors a bit more. This removes an overflow hidden on the value side, but that shouldnt cause any issues, given it has plenty of space.

Test Plan: tested differential and audit, highlighted and not.
