Dashboards: Fix react-grid-layout placeholder stuck when dragging panel across rows

Browse Source 
Toggle isDraggable off/on when removing a panel from SceneGridLayout to force
react-grid-layout to exit drag mode and clear its internal state. This prevents
the placeholder from remaining stuck when dragging panels from a custom grid
inside a row to another layout.
