EQM: Resource selection navigation & messaging bugs

[nucleogenesis]

Overview

Related in part to #12292

Reported by @marcellamaki here in Notion - I have also replicated some of these issues.

• The X of Y questions values are not being updated upon selection of children resources (ie, I select a resource, then go up a level, the folder with that resource still says 0 of whatever)
• A selected folder does not update it's "x of y questions selected" text

At a high level, the resource selection needs to be made to be up-to-date with the guidance we expect to come from the final pass on strings tomorrow.

Also, see this post by Marcella as well

Here she got into a situation where she cannot add items:

Related to open “state” bug, I can get myself into a situation where I have selected resources but can’t actually save/add and move forward
