✨(Account Abstraction) Enable WebAuthN/PassKey signatures

[Nakasar]

Changelog

• Upgrade solidity to latest version .27
• Upgrade hardhat toolsuite (migrate ethers utilities).
• Enable account abstraction for ONCHAINID identities by allowing users to execute/approve using webauthn/passkey (secp256k) keys.
• Enable account abstraction for ONCHAINID identities by allowing users to execute/approve using ECDSA keys.

Added

• Identity now has a payable fallback receive method. (Fund can always be retrieved from Identities using execute/approve flow).
• Identity now implements an executeSigned method. It behaves the same as the execute method except it accepts a signature for validate permissions. Signature is composed of keyType (from Key type mapping integers), v, r and s. This method supports ECDSA keys (keyType 1) and P256 keys (keyType 3) for webauthn.
  • Signature is an Ethereum Signed Message of keccak256(abi.encode(identityAddress, _to, _value, _data)) (⚠️ add nonce or equivalent to prevent replays).
• Identity now implements an approveSigned method. It behaves the same as the approve method except it accepts a signature for validate permissions. Signature is composed of keyType (from Key type mapping integers), v, r and s. This method supports ECDSA keys (keyType 1) and P256 keys (keyType 3) for webauthn.
  • Signature is an Ethereum Signed Message of keccak256(abi.encode(_identityAddress, _executionNonce, _to, _value, _data)).
