[Risk mitigation] Redefine integration extension

[schmanu]

What is the feature about

In our initial risk mitigation module / integration we scan the transaction data.

We should extend this integration by

• Scanning EIP-712 message requests: With off-chain integrations growing, these messages can contain harmful payloads which can potentially steal funds / nfts.

The list of requirements

• scan off-chain messages: Our new off-chain message modal should also send a scan request with the message as payload.

@katspaugh I removed the requirements around passing the domain to redefine as WalletConnect now includes their own domain check and we revamped our WalletConnect connection widget with those warnings.
