fix: Only increment payment attempts when user actually attempts payment

- Remove payment attempt increment from checkout page load
- Add new increment_payment_attempt action triggered only on pay button click
- Update checkout JavaScript to make AJAX call before Stripe redirect
- Add proper error handling and button state management
- Prevent inflated payment attempt counts from page refreshes

This ensures payment attempts accurately reflect actual payment tries rather than page visits.
