[24.2] Fix activity-bar-id handling wrt activityStore

[dannon]

Debugging something else, I noticed that we were creating extraneous/duplicate activity stores. There should be two, the new workflow editor bar and the default (analysis view) bar. We were unintentionally creating separate ones for upload, notifications, and interactive tools due to reuse of the wrong 'id' to name the store.

I'm not positive this was causing specific issues, but I wouldn't be surprised if it was to blame for some categories of glitches in changing activities and clicking on the bar.

Example of duplicate store arrangement/contents:
