CVE-2026-47745: Shopper: Missing per-action authorization on PaymentMethods, Currencies and Carriers admin tables

The admin tables for PaymentMethods, Currencies and Carriers exposed inline toggles and per-record actions (enable, disable, edit, delete) that were rendered for any authenticated panel user without checking the corresponding per-action permission. A low-privilege user could:

• Disable every payment method on the store, blocking checkout.
• Disable or alter the default currency, changing displayed prices and the exchange rate basis.
• Disable carriers, breaking shipping rate computation at checkout.

The impact is a full denial of checkout and pricing integrity loss, reachable by any authenticated user.
