/**
* Tom's Java Jive - Apply Wallet Credit / Gift Card at Checkout
*
* Validates and quotes an amount to apply toward the current order total.
* Does NOT deduct wallet balance here - that only happens once the Square
* payment actually succeeds (see markSquarePaymentResult() in
* includes/square.php), so an abandoned checkout never loses a customer's
* real wallet money. A gift card code, if given, is redeemed into wallet
* balance immediately (same as the Wallet page does) since that step is
* safe/reversible-in-spirit - only the *spending* of wallet balance at
* checkout is deferred to payment success.
