Workflow: "Changes" list of actions should highlight unresolved items that are preventing a save

[jennaj]

Describe the bug
Saving a workflow can be blocked by unresolved items on the workflow canvas.

If the user did something that is captured in the changes listing that is part of that save blocking, and the canvas item is in red with a warning, that action in the change list should also be highlighted in red.

Love the Changes redo/undo overall! And also like the save blocking for unstable changes. These are just some ideas to make the usage easier!

To Reproduce
Steps to reproduce the behavior:

1. Go to a workflow in the editor
2. Do something that prevents a save, such as adding a sub-workflow that is not owned (example).
3. Try to save the workflow, get the message about the problem.
4. Go to your changes listing -- good luck! Which item is the problematic item isn't clear.
5. Presumably we know which that is, yes? Highlighting it would be great. Even better, also add that exact item to the warning, and tell the user to look under their Changes. This is how tool warnings appear during workflow imports -- maybe can reuse that same view here?
6. Any other problematic items that were already resolved by the user and not blocking the save should not be highlighted.

Expected behavior
Change items blocking a save are clearly highlighted so the user can find and undo those.

You should not be able to add someone else's workflow here, if other people's workflows are listed in an admin's workflow acitivity that would be quite the bug (independently of highlight changes that are potentially at fault).

I was just in a regular non-admin account. :)
