feat/fix: App mode QA feedback 2 (#9511)

## Summary

Additional fixes and updates based on testing

## Changes

- **What**: 
- add warning to welcome screen & when sharing an app that has had all
outputs removed
- fix target workflow when changing mode via tab right click menu
- change build app text to be conditional "edit" vs "build" depending on
if an app is already defined
- update empty apps sidebar tab button text to make it clearer
- remove templates button from app mode (we will reintroduce this once
we have app templates)
- add "exit to graph" after applying default mode of node graph
- update cancel button to remove item from queue if it hasn't started
yet
- improve scoping of jobs/outputs to the current workflow [not perfect
but should be much improved]
- close sidebar tabs on entering app mode
- change tooltip to be under the workflow menu rather than covering the
button
