Verify the payment for a reservation created with instant charge

Verify the payment for a reservation created with instant charge when Guesty Pay is used. It should be called immediately after the /instant-charge endpoint when the returned payment has status PENDING_AUTH. If the 3DS verification succeeds, the payment is charged and the reservation is confirmed. If the verification fails, the reservation is closed.

For providers with GuestyPay protect, the threeDSResult object is returned from the SDK handle3DSChallenge fuction and it should be sent here for 3DS challenge verification. If GuestyPay in EU/UK, this object is not necessary.
