DCE: Optimize options exercise and hedging businesses.

DCE: Add the option surrender application, option buyers can directly express their willingness to not exercise the option contract on the expiration date, and cancel the "automatic exercise application on expiration date" function. After the market closes on the expiration date, for option positions that have not been exercised or surrendered within the specified time, the exchange will handle them as follows: if the exercise price is lower than the settlement price of the underlying futures contract on that day, the long call option position will be automatically exercised; if the exercise price is higher than the settlement price of the underlying futures contract on that day, the long put option position will be automatically exercised; all other option positions will be automatically surrendered.
