Diff introduces a hook to check if there is information about not acknowledged policies in login response and dispatch an action if needed.
Additionally, it removes data from the response to not share data with user until acceptance.
Probably I'll wait with landing this until most of the SIWE feature will be ready to test end-to-end how this change works with login using wallet.
