feat: Block Lighthouse cryptic user agent

Believe it or not, this is Lighthouse's user agent. They don't usually include "lighthouse" in it anymore because some people were gaming the system for LH scores, so they use some cryptic UAs now. I'll just ignore this outright because not many people will actually have that UA, and this might cause some big bills for some customers.
