Prevent Duplicate Item Addition When Scanning on POS

Currently, when scanning an item on the POS, the system adds the scanned item to the cart but also displays a drop-down suggestion for the same item. This can cause confusion for users, as they may instinctively click the drop-down option, resulting in the same item being added twice to the cart. To improve the user experience and avoid duplicate additions, we suggest refining the POS behavior so that once an item is scanned and automatically added to the cart, the drop-down suggestion for the same item does not appear. This enhancement would make the scanning process more intuitive, reduce human error, and streamline checkout operations for store staff.
