ApplePayButton doesn't appear in production

Describe the bug
The ApplePayButton widget is not rendering or is unresponsive in the production build of the app. This issue, identified by the App Store review team, is preventing app submission. The button functions correctly in debug and development builds.

To Reproduce
Steps to reproduce the behavior:

1. Add ApplePayButton to your app
2. run the app on physical device
3. navigate to the payment screen in the production app.
4. the ApplePayButton widget does not appear or is not responsive to taps.

Expected behavior

Additional context
The issue is exclusive to the production environment.
The app was rejected by Apple, with the specific error: "unresponsive."
The payment flow works correctly in debug and development environments. This strongly suggests a misconfiguration related to production entitlements or certificates.

Start with the ApplePayButton integration and compare its production build behavior with the working debug and development builds on a physical device. Check the production entitlements or certificates implicated by the report; done means the native Apple Pay button renders, responds to taps, and presents the payment sheet in the production app.
