//! Mode-specific reporting functionality for different trading modes
//! 
//! This module provides specialized reporting capabilities for backtesting,
//! paper trading, and live trading modes. It includes performance metrics,
//! real-time monitoring data, and funding rate impact analysis across all modes.
