 * Bridge charge method for MPP — shared schema used by both server and client.

 * the bridge settles on the merchant's target chain (e.g. SKALE).
 *
 * Composable with direct evm/charge methods via Mppx.compose() — the client
 * receives both challenges and picks direct payment if it has the right wallet,
 * or bridge if it needs cross-chain routing.
