Integrate window traffic lights into app chrome

Use fullSizeContentView with a transparent title bar so the system
close/minimize/zoom controls sit on the dashboard chrome. Hide the
title bar text, set the window title to App for Indeed, and pin the
main content stack to the safe area so layout stays clear of the
controls. Enable dragging from the window background.
