Fix: Window manager view check reads stale state after restore

The window manager's "view" action checks the window state against the
ItemData.Data[2] field populated when the list was built. The right-click
show/hide/maximize/minimize handlers updated only the list control's display
text via SetItemText, leaving Data[2] stale. After restoring a minimized
window, viewing still reported "该窗口已最小化" until the dialog was reopened.

Sync Data[2] alongside SetItemText in all four handlers so the view check and
the status-column sort both see the current state.
