Add loyalty redemption product to guest reservation record

Reservations with loyalty redemptions often lack posted charges, causing manual billing fixes at checkout. This posts the redemption product so charges and reports are accurate before checkout.

Overview

Loyalty redemptions often arrive as notes and go unposted, creating late billing corrections and extra work for your revenue team. This flow reads reservations, extracts the redemption amount, and posts the product charge so invoices and reports are correct before checkout.
