…ictions Implement node-level V3 billing opt-out mechanism allowing farmers to exempt nodes from billing while restricting deployments to authorized twin admins. Add storage maps for opt-out tracking and admin list management. Include billing suppression logic for opted-out nodes in Created state, with zero-cost calculations for both standard and additional fees.
Implement client methods for V3 billing opt-out functionality including OptOutOfV3Billing, AddTwinAdmin, RemoveTwinAdmin, GetAllowedTwinAdmins, and IsNodeOptedOutOfV3Billing. Add corresponding event types NodeV3BillingOptedOut, TwinAdminAdded, and TwinAdminRemoved. Include comprehensive unit tests and update error definitions for new tfgrid and smart contract module errors.
