App mode - more updates & fixes (#9137)

## Summary

- fix sizing of sidebars in app mode
- update feedback button to match design
- update job queue notification
- clickable queue spinner item to allow clear queue
- refactor mode out of store to specific workflow instance
- support different saved vs active mode
- other styling/layout tweaks

## Changes

- **What**: Changes the store to a composable and moves the mode state
to the workflow.
- This enables switching between tabs and maintaining the mode they were
in
