feat(ui): Simplify dashboard to reflect root-only architecture

Update the dashboard UI to align with the new root-only application model.

- The conditional logic for displaying "Install Mode" has been removed from `render_dashboard`.
- The display is now hardcoded to always show "Chroot (Full Access)", as PRoot is no longer a supported mode.
- Minor refactoring of the text layout for better clarity.

This change simplifies the UI code and removes potentially confusing information for the user, providing a more accurate system diagnosis.
