Allow Stripe Elements to be loaded for custom checkout flows

[therealstein]

I'm requesting the ability to load Stripe Elements—particularly the credit card field element—so developers can integrate their own checkout flow with RevenueCat subscriptions. While I appreciate the platform's user management features, I've experienced issues with the current purchasing flow: I recently lost 7 out of 10 purchases due to the unclear error message "Error processing purchase." The dashboard showed no logs for affected users, nor did Stripe's dashboard. This makes troubleshooting very difficult and creates a frustrating experience.

It feels unstable at times, especially with recent updates that defer or revert Stripe loading. Having the option to directly integrate Stripe Elements would allow for more reliable and transparent checkout experiences, improve developer confidence, and reduce lost sales due to errors.
