App mode mobile redesign (#9047)

Reworks the app mode display for mobile devices. Adds multiple bottom
tabs that can be swiped between.


![AnimateDiff_00005](https://github.com/user-attachments/assets/e1c928ff-dd52-4f4c-83a6-c351c4711e62)

To be handled in followup PRs
- Nicer error display
- Support for even smaller screens
- UX improvements for the 'Outputs' pane
  - Was postponed to minimize conflicts with non-mobile development.
