/**
 * Web3Auth-integrated x402 fetch hook.
 *
 * Automatically selects the correct payment path based on the currently connected
 * chain namespace:
 *  - **Solana** - uses `createSolanaX402Fetch` backed by the web3auth Solana wallet.
 *  - **EVM** - uses `createEvmX402Fetch` backed by the web3auth EIP-1193 provider.
 *
 * Callers do not need to pass a signer manually; it is sourced internally.
 * When `address` is provided, it takes precedence over the provider's active account.
