Subject: [PATCH] Fix zero amount sent to SaferPay API for products with
 dynamic pricing

Pre-compute cart total before order creation to prevent third-party
modules from affecting the amount sent to SaferPay Initialize API.
When order creation rule is "Before authorization", validateOrder
triggers hooks that can clean up dynamic pricing data, causing
subsequent cart total reads to return 0.
