Comprehensive test suite for advanced order type semantics: +//! - IOC (Immediate-Or-Cancel): Execute immediately, cancel remainder +//! - FOK (Fill-Or-Kill): Execute completely or reject entirely +//! - Iceberg Orders: Display quantity with hidden reserves +//! - Post-Only Orders: Maker-only execution, no taker fills +//! - GTD (Good-Till-Date): Time-based expiration handling +//! +//! Note: These tests simulate advanced order type behavior since the current +//! OrderManager implementation doesn't have specialized logic for each type. +//!
