PanelShell class

The one-widget panel: sidebar/rail/drawer, master list and detail pane, laid out by form factor (P23).

compact: a Scaffold with the resources in a drawer and a nested Navigator pushing list → view → form, exactly the wiring the example host used to do by hand.
medium: a NavigationRail in place of the drawer; same single pane.
expanded: sidebar | master list (row style, selection highlighted) | detail pane with its own nested Navigator, so relation flows push inside the pane and never lose the list.

All three read one state — the selected resource and record — so a window crossing a breakpoint keeps what the user was looking at.
