Secondary Wallet Attestation Implementation

[sshubhamagg]

1. Implement attestation function:

function attestSecondaryWallet(
    uint256 id,
    address secondaryWallet,
    bytes memory primarySignature,
    bytes memory secondarySignature
) external onlyRegistrar

2. Implement dual signature verification:

function verifyAttestationSignatures(
    uint256 id,
    address secondaryWallet,
    bytes memory primarySignature,
    bytes memory secondarySignature
) internal view returns (bool)

Requirements:

1. ID must exist
2. Secondary wallet must not be registered
3. Both signatures must be valid

Events Emitted:

event AttestationCompleted(
    uint256 indexed id,
    address indexed primaryWallet,
    address indexed secondaryWallet
);

event AttestationFailed(
    uint256 indexed id,
    address secondaryWallet,
    string reason
);
