Frans Gift Card features:
1/ Order placement:
- Applying or removing a gift card immediately recalculates and persists the quote total instead of waiting for the
item update button
- Stripe charges only the remaining amount after the gift card deduction
- Gift card is redeemed through Square when the order is placed, and the balance is deducted correctly.

2/ Refund:
- If an order with a gift card receives a credit memo, the refunded gift card amount is added back to the Square gift card.
