 * Handles WS Form submission and maps form fields to FunnelKit optin fields dynamically.

 * WS Form fields to logical optin fields (first name, last name, email, phone) by inspecting the form's
 * structure and matching on field type and label. This approach is robust to field reordering and renaming.
 *
 * @param WS_Form_Submit $submit The WS Form submission object passed by the action hook.
