Subject: POS Transactions can be saved in a CLOSED shift if two instances of POS is used on the same machine by the same user

Users can open two POS applications on the same machine. If a Shift is closed in one POS Application, the system allows the second application to continue processing on this closed shift.

Users should not open TWO POS Applications on the same machine for POS processing, however, to prevent the issue we will introduce a check to prevent orders from being saved into a CLOSED shift.
