Walkthrough

The changes introduce a new RpcExtras utility class to encapsulate coin-specific RPC parameters for withdrawal operations. The class provides a withdrawForCoin method that returns KMD-specific rewards configuration, while other coins receive empty parameter maps. The WithdrawRequest is updated to integrate these extras into its JSON serialization.

Changes

Cohort / File(s)	Change Summary
New RPC Extras Utility lib/mm2/mm2_api/rpc/rpc_extras.dart	New utility class RpcExtras with constant kDefaultKmdRewardsAmount and static method withdrawForCoin that returns coin-specific RPC parameters—KMD returns kmd_rewards configuration, other coins return empty map
Withdraw Request Integration lib/mm2/mm2_api/rpc/withdraw/withdraw_request.dart	Added import of RpcExtras, integrated withdrawForCoin call to retrieve coin-specific extras, and updated toJson to merge extras into top-level JSON map
