Show UUID and icon serial number in the advanced tab

**Is your feature request related to a problem? Please describe.**
No.

**Describe the solution you'd like**
Show UUID and icon serial number in the advanced tab.

**Additional context**
When the UUID option in settings is enabled, UUID is shown everywhere and also in the advanced tab. However, we can just always show the UUID in the advanced tab, and that setting option is not that necessary then.

Start by locating the advanced tab UI and the existing UUID display logic, including how the UUID setting controls visibility. Update the advanced tab so it always shows the UUID and also shows the icon serial number; done means both values appear there regardless of the UUID setting.
