Address PF5-related UI issues

[jenny-s51]

Towards comments in #2041 , most of those issues are fixed with these changes here.

This popover issue requires more investigation and potentially more significant updates to components/logic - marking this PR as a draft for now as I look into a fix here. Fixed ✅

Also will be looking at tests to see the scope of work that will be required - more assistance may be needed, TBD

Description

How Has This Been Tested?

Test Impact

Request review criteria:

Self checklist (all need to be checked):

• The developer has manually tested the changes and verified that the changes work
• Commits have been squashed into descriptive, self-contained units of work (e.g. 'WIP' and 'Implements feedback' style messages have been removed)
• Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
• The developer has added tests or explained why testing cannot be added (unit tests & storybook for related changes)

If you have UI changes:

• Included any necessary screenshots or gifs if it was a UI change.
• Included tags to the UX team if it was a UI/UX change (find relevant UX in the SMEs section).

After the PR is posted & before it merges:

• The developer has tested their solution on a cluster by using the image produced by the PR to main
