TListDetail<T, K> class
A master-detail split layout widget that displays a list of items on the left and details of the selected item on the right.
TListDetail is responsive: on wider screens it splits the screen into a sidebar
list and a details pane, while on narrower (mobile) screens it behaves like a navigation stack.
