/**
 * Executes an EVM checkout transaction by handling optional ERC-20 approval
 * and sending the main swap transaction on-chain.
 *
 * 1. Validates that the wallet account is an EVM wallet account
 * 2. If the signing payload includes an `evmApproval`, checks the current
 *    ERC-20 allowance and sends an approve transaction when insufficient
 * 3. Sends the main transaction using the viem wallet client
 *
 * @param params.signingPayload - The chain-aware signing payload containing `evmTransaction` and optional `evmApproval`.
 * @param params.walletAccount - The wallet account used to sign and send transactions.
 * @param params.onStepChange - Optional callback invoked with `'approval'` or `'transaction'` as each step begins.
 * @param client - The Dynamic client instance.
 * @returns The main transaction hash and, if an approval was sent, the approval transaction hash.
 * @not-instrumented
