P2 Badge Use a chain ID that matches the escrow contract

This appendix challenge now pairs chainId 4217 with escrow contract 0x9d136e..., but the deployed-contracts table in this same draft lists that address only for Moderato testnet chain 42431. Clients using this example to build the EIP-712 domain would verify/sign against the wrong network-contract pair, making the example unusable unless a 4217 deployment address is added or this example remains on 42431.
