Highlight deltas between base and patch status for tasks and tests

We already partially do this as of EVG-13365, since we sort patch=failed, base=success tasks to the top. It would be great if we could more generally highlight deltas in status between the base and patch builds, e.g., patch=success and base=failed, to confirm whether a failure has been addressed in the patch build. Presently, patch=success and base=failed get sorted to the end of the tasks list by default.
