Minor rounding change for custom line item discounts in POS 11.5

Starting with POS version 11.5, we are updating the internal calculation method for custom fixed-amount line item discounts. These discounts will now be applied on a per-unit basis rather than across the entire line. Note that this change only affects fixed-amount discounts; percentage discounts remain unchanged.
