Add support for Work Profile apps

[sonalder-darlene]

Is your feature request related to a problem? Please describe.
I am interested in daily driving Stario on my main Android device however I use Work Profile (through Shelter) a lot and rely on it to better compartimentalized my apps. It is a native Android feature similar to the newly introduced Private Space in Android 15 mainly made for companies to have a entreprise phone within their employee's Android phones. It is the first time I use a launcher that wasn't able to show them to me or add them to homescreen. They are usually differenciate with a small briefcase icon.
You can create them on most devices (or ROMs/Android flavors) using Shelter or Insular apps or natively on CalyxOS using their own WorkProfile App.

Describe the solution you'd like
Either a new "Work Apps" slide next to the Regular Apps slide or within the same slide but with the small briefcase icon. I think the briefcase icon is necessary either way and probably handle by Android itself.

Describe alternatives you've considered
Using another launcher :)
