fn get_nonce(env: soroban_sdk::Env) -> u64Read the stored passkey pubkey (for debugging/verification).
fn get_passkey(env: soroban_sdk::Env) -> soroban_sdk::BytesN<65>Constructor: Automatically called during deployment Initializes the contract with the passkey secp256r1 public key (65-byte uncompressed), the DeFindex vault contract address, and the USDC token address.
fn __constructor(

)Transfer USDC from this contract to a recipient address. Only the registered passkey can authorize.
auth_data and client_data_json come from the WebAuthn assertion.
The signature is over SHA256(auth_data || SHA256(client_data_json)).
The challenge inside client_data_json must equal SHA256("transfer_usdc" | amount | nonce).
