Erik 3d04f61451 feat(ui): D.5.3/B.1 — toolbar drag handler stub + spine wiring (TS-33) ... Implements Task 4 of the drag-drop spine: ToolbarController now satisfies IItemListDragHandler. The ctor loop wires RegisterDragHandler(this) on every slot list and stamps Cell.SlotIndex + Cell.SourceKind=ShortcutBar, matching retail's gmToolbarUI::PostInit/RegisterItemListDragHandler pattern. OnDragOver accepts any non-empty payload (TS-33 stub; eligibility gate is Stream B.2). HandleDropRelease logs and returns (no AddShortcut 0x019C / RemoveShortcut 0x019D wire yet). Three new B.1 xUnit tests cover handler registration, accept, and inert-stub semantics. All 490 app tests pass.
