order_cleanup.rs

//! Integration tests for the order_cleanup contract — verifies that
//! `cancel_expired_order` correctly delegates to `order_handler::cleanup_expired_order`
//! and that a permissionless caller (not the order owner, not a keeper) can cancel
//! an expired order and receive the incentive.
//!
//! This covers the authorization bug where `cancel_expired_order` previously called
//! `cancel_order` with the helper contract address, which would revert with
//! `Unauthorized` because the helper is neither the order owner nor an ORDER_KEEPER.
