Expected to resolve https://github.com/blockscout/frontend/issues/2140

I have tested these changes locally and on the demo, but it looks like nothing is working. I was only able to log in through Farcaster (and that with errors). When logging in via other social networks, the loader appears, the window with login to the social network opens, and the loader disappears immediately without waiting for me to log in (and if I finally log in, nothing happens, of course).
