Logs an error message with automatic red color or custom color and component.

Usage

// Automatic color (red)
log_error!("Failed to connect to exchange: {}", error);

// Custom color
log_error!("Custom error message", color = LogColor::Magenta);

// Custom component
log_error!("Connection failed", component = "DataEngine");

// Both color and component (flexible order)
log_error!("Critical error", color = LogColor::Magenta, component = "DataEngine");
log_error!("Critical error", component = "DataEngine", color = LogColor::Magenta);
