feat(position_manager): Improve monitoring logic for Binance positions without SL/TP orders

Updated the position monitoring logic to handle cases where positions exist on Binance without corresponding stop-loss or take-profit orders. Enhanced logging to provide clearer insights into the status of these positions, ensuring better risk management by avoiding unprotected positions. This change allows for automatic monitoring and order creation based on the presence of SL/TP orders.
