layout: add missing groupbar decoration to the window (#3235)

Browse Source 
* fix: add missing groupbar decoration to the window

Add groupbar decoration to the operand window of `CWindow::insertWindowToGroup` if it does not exist, to prevent segmentation faults when mouse events are triggered after moving the window to a group, where `getDecorationByType(DECORATION_GROUPBAR)` unexpectedly returns nullptr.

Also fixed a bug where the group bar disappeared when the moveIntoGroup dispatcher's operand window was in a group.

* Update Window.cpp
