PdfPanelDragScope class
Ambient wiring that lets a docked panel's move handle drive the shell's
drag-to-redock affordance. PdfShellPanelLayout provides it around the
panels; a panel's PdfSidebarPanelGeometry.moveHandle reads it. Absent
when a shell wires no redocking - then panels render no move handle.
