Rewrite the backend in Typescript

[ahaym]

I wrote the backend in Haskell because that's what I'm most familiar with. Not a joke, look at my Github/Linkedin.

I acknowledge that Haskell is a rather difficult language. It might be easier for new contributors if the backend was in Typescript. We'd also be able to conveniently distribute through npm instead of docker.

The backend is not complicated, so this should be pretty easy. GPT-4 might even be able to do most of it.
