🐛 Fixed a bug where promotion stock wasn't held for pending orders

This meant a promotion could sell out while the checkout journey was completing, so when the payment was confirmed the promotion stock hadn't been reserved for the order.

🐛 Fixed Global Payments Bug

Fixed a bug where the global payments payment gateway was making multiple pending orders instead of just one.

🐛 Fixed out of stock promotion message

If promotion stock has run out when a customer makes a payment, the validation error was generic saying 'an error has occurred', now it states that the promotion is no longer valid.
