Improve UX and messaging for certain errors when landing revisions

Summary:
Ref T9994.

  - Allow errors to be dismissed.
  - Tailor messaging for closed/abandoned revisions.
  - Reduce scare messaging on land dialog, since it's not really that scary anymore.

Test Plan:
  - Dismissed errors.
  - Hit new warnings.
  - Wasn't as scared when landing.
