RequiredBillingContactField
Billing contact fields that the SDK can collect on the new-card payment screen and validate in the headless checkout path. Mirrors iOS's AWXRequiredBillingContactFields option set.
Scope: card payments only. This setting drives the card-entry UI and the headless-checkout billing validation for cards. It does NOT propagate to Google Pay or other LPM (Local Payment Method) flows — Google Pay's billing contact is configured separately through com.airwallex.android.core.GooglePayOptions (billingAddressRequired, billingAddressParameters, emailRequired).
Configure via AirwallexSession.requiredBillingContactFields. An empty set hides the entire billing section; null (the default) derives the set from the legacy AirwallexSession.isBillingInformationRequired / AirwallexSession.isEmailRequired flags so existing integrations keep their current behavior.
ADDRESS and COUNTRY_CODE are mutually exclusive in the UI: when both are set, ADDRESS wins and the standalone country picker is suppressed.
