Enable WC social login

[maikReal]

What to do?

We need to enable the social login for the WalletConnect widget. But before enabling it, we need to check what will be the result of a wallet connection if a user is using "Sign in with Farcaster". As for the BS account v2 we need to have a wallet address and the signature to create a BS account, we need to have the same info if a user uses the social login

For BS account V2:

• WC creates an EOA address by social login, seems we need to request a window where a user can sign a message

@maikReal @tom2drum I tested this feature, but it doesn't seem to work. More details in the PR description: https://github.com/blockscout/frontend/pull/2159
