Issue:
Bug: [REFACTOR] enable ORF feature for Fiuu connector for FPX payment methods



ORF feature for refunds allows skipping mandatory information required for refunds, like - beneficiary's name, bank code and other details.

Currently, HS integration for Fiuu sends this field during refund initiation. This needs to be omitted for using the ORF feature.
