Support multiple batch preview menus on canvas

Browse Source 
Refactored batch preview management to allow multiple BatchPreviewManager instances per canvas. Updated positioning logic to use an initial spawn position, adjusted UI updates, and ensured batch preview menus move correctly with canvas panning. Removed single-instance references and updated related event handling.
