…rules (#225939)

## Summary

Addresses #207172

Follow-up to: #219628

Adds per-field badges to the rule details page so that users can see
which fields are modified on their customized prebuilt rules. Clicking
on the badges opens a rule diff flyout that displays more extensive
information.

Also switches the concurrency controls in the flyout to a static view in
which data doesn't change when it is stale, we just now display a
callout informing the user that the information they're viewing is
outdated.

### Screenshots
