Subject: modules/bookwyrm: init

this should be mostly usable for actual deployments. Only thing that's
really still annoying is having to set the SECRET_KEY via Nix, since
not having set it makes the package fail to build. But it doesn't
actually end up in the derivation, so changing it afterwards should be
fine; I've just not tested that yet.
