Add flag reason to flagged pieces in inspect

[jacobheun]

Summary

When a piece is flagged for an SP to review, it's not clear why (see screenshot below) it was flagged. We should include a reason when a piece is flagged so it's clearer what Action an SP should take to fix any potential problems. We should also ensure there's a clear way for SP's to mark flags as resolved or dismiss them if possible and not done automatically.
