feat/fix: App mode QA updates (#9439)

## Summary

Various fixes from app mode QA

## Changes

- **What**: 
- fix: prevent inserting nodes from workflow/apps sidebar tabs
- fix: hide json extension in workflow tab
- fix: hide apps nav button in apps tab when already in apps mode
- fix: center text on arrange page
- fix: prevent IoItems from "jumping" due to stale transform after drag
and drop op
- fix: refactor side panels and add custom stable pixel based sizing
- fix: make outputs/inputs lists in app builder scrollable
- fix: fix rerun not working correctly

- feat: add text to interrupt button
- feat: add enter app mode button to builder toolbar
- feat: add tooltip to download button on linear view
- feat: show last output of workflow in arrange tab if available
- feat: show download count in download all button, hide if only 1 asset
to download

## Review Focus

- Rerun - I am not sure why it was triggering widget actions, removing
it seemed like the correct fix
- useStablePrimeVueSplitter - this is a workaround for the fact it uses
percent sizing, I also tried switching to reka-ui splitters, but they
also only support % sizing in our version [pixel based looks to have
been added in a newer version, will log an issue to upgrade & replace
splitters with this]
