feature: decouple strategyData from GenericSwapData

[alex0207s]

strategyData is time-sensitive, and including it in the GenericSwapData struct would make the entire order time-restricted. By decoupling strategyData, the order becomes more flexible, ensuring that the user's intent to exchange tokens remains unchanged while avoiding the need to repeatedly sign the same exchange intent with different strategyData.
