OwnableValidator Forces EIP-191 Signature Format, Preventing EIP-712 Typed Data Support

[johnson86tw]

The OwnableValidator contract hardcodes the use of ECDSA.toEthSignedMessageHash() in its signature validation logic, which forces all signatures to use the EIP-191 personal message format. This prevents users from signing structured EIP-712 typed data.
