Add embeddedAuth method to Universal Verifier

[daveroga]

Currently we check Auth in both authResponse with authV2 method (authV2 circuit) and all the responses for request validators (on-chain credential query validator circuits).

We will add a embeddedAuth auth method for the authResponse that won’t verify the auth proof because we already are verifying embedded auth in responses for on-chain circuits now.

This will allow:

• Save some gas in submitResponse for verification
• Verify in some networks like Aurora that have a maximum gas limit that we are exceeding now verifying both authResponse and responses proofs.

Pull Request Overview

This PR introduces a new noAuth authentication method to the Universal Verifier system to reduce gas consumption and enable deployment on networks with gas limitations like Aurora. The implementation allows verification to proceed without an authentication proof since authentication is already verified in the response proofs for on-chain circuits.

• Adds noAuth authentication method that skips auth proof verification
• Modifies verifier logic to handle authentication differently based on method type
• Updates deployment scripts and tests to support the new authentication method

Using a local file path dependency for @0xpolygonid/js-sdk instead of a published version can cause issues in CI/CD and for other developers. Consider using a published version or a git URL with a specific commit/tag.

Suggested change

	"@0xpolygonid/js-sdk": "../../polygonid/js-sdk",

The aurora-mainnet network is configured to use AURORA_TESTNET_RPC_URL instead of AURORA_MAINNET_RPC_URL. This should be process.env.AURORA_MAINNET_RPC_URL.

Suggested change

	url: `${process.env.AURORA_TESTNET_RPC_URL}`,
	url: `${process.env.AURORA_MAINNET_RPC_URL}`,

The hardcoded chain ID (1313161555) and network configuration should be extracted to constants or made configurable, as this script appears to be for testing custom networks but has Aurora-specific hardcoded values.

Suggested change

	async function testVerification(verifier: Contract) {
	// Register the DID method for your custom network
	core.registerDidMethodNetwork({
	method: core.DidMethod.Iden3,
	blockchain: "aurora",
	chainId: 1313161555,
	// Configurable network parameters
	const NETWORK_BLOCKCHAIN = process.env.NETWORK_BLOCKCHAIN || "aurora";
	const NETWORK_CHAIN_ID = parseInt(process.env.NETWORK_CHAIN_ID || "1313161555", 10);
	async function testVerification(verifier: Contract) {
	// Register the DID method for your custom network
	core.registerDidMethodNetwork({
	method: core.DidMethod.Iden3,
	blockchain: NETWORK_BLOCKCHAIN,
	chainId: NETWORK_CHAIN_ID,

Several import statements were removed but the functionality appears to still be needed. The getDeployedAddresses function was removed but may be used elsewhere in the deployment process.

Suggested change

	import { getConfig, getDeploymentParameters } from "../../../helpers/helperUtils";
