fix: handle dynamic form IDs in Bizum create_hidden_input

jimmyn · jimmyn · commit bd25b6b6104f · 2025-10-10T12:36:37.000+02:00
- Try primary form ID (monei-bizum-form) first
- Fall back to order-pay form ID (wc-monei_bizum-cc-form)
- Only append hidden input if target element exists
- Add error logging for missing form container
- Prevents exceptions that could block payment submission in order-pay flow
