[Cashtab] Add corporate scams to agora blacklist

Summary:
Getting to the point where very clearly I will need to get a better / more automated system

I think icon approval and agora approval should be listed, since almost every token with a bad icon should also be blacklisted.

Will need some more thought and probably a light database on token-server

Test Plan: npm test
