feat: Update the design for dashboard_apps (#9840)

This PR migrates the dashboard apps page to the new layout and includes
the following updates:

- Create a compact design for the back button
- Add a back button to the settings header
- Reduce letter-spacing on the description
- Fix mobile styles
- Migrate the layout of dashboard apps/index to new layouts


Note: I've moved all feature help URLs from features.yml to the frontend. This change prevents features.yml from becoming bloated due to frontend modifications.
