     * Prepare and normalize the incoming data before validation.

     * This method ensures that each variant in the request payload has the necessary structure
     * expected for processing, particularly focusing on the `other_info` attribute.
     *
     * If `other_info` is missing from a variant (common during data migration scenarios),
     * this method sets default values to prevent validation or processing errors.
     *
     * It also ensures that:
     * - `fulfillment_type` is consistently applied across all variants, defaulting to 'physical'.
     * - `payment_type` is set (defaulting to 'onetime') and injected into `other_info`.
     * - `other_info` is populated with a consistent structure containing default billing and setup fee options.
     *
     * @return array The normalized request data ready for validation.
