[Redesign] Provide more color to object states in headers

Summary: Ref T8099, Now that we have cleaner headers, we can add more pop to important items, like the state of an Object. This makes it easier to just note the color and generally understand the state of the object (closed, returned, accepted, open). @epriestley, I think you previously thought this was a bug, but if it still feels bad, let me know.

Test Plan:
Review Differential, Maniphest, Polls for various object states.
