This PR contains a bunch of small fixes having to do with infra code. The goal is not to fix everything as that would require a full rewrite. Instead, we fix just what is necessary to get some testing going on. Once that is available, we will be able to work on a full refactor with more guarantees. Something of note is that most of the difficulty was to find code that would make both `nixops4 apply` _and_ `nix build .#nixosConfigurations.<machine>` happy. The takeaway is that the tests that we are adding now will not catch a whole class of tests having to do with how NixOps4 wires up the resources. Still, this is probably less significant as we are supposed to use NixOps4 every now and then.

The commits should be read separately.

Following Fediversity/Fediversity#478 (comment), here is a PR that plugs the infra's `vmOptions` and `nixosConfigurations` outputs into flake checks, instead of calling random Nix commands from the CI. There is still a bit of magic in the CI, but that's because we don't have yet a Nix-aware CI that exposes one job per flake check.

Closes #103

At last, a fully fledged data model for what Fediversity really is and does. This comes with a test that exercises a very simple but functionally complete arrangement with all ingredients fo the business logic: a dummy resource (login shell), a dummy application (`hello`, which needs a shell to live in), a dummy environment (a single NixOS VM that allows for one, the operator's, login shell), and a deployment of that environment given a dummy configuration (that enables `hello`).

The next step will be to lift this purely evaluation-level test into a VM test which verifies that the resulting VM indeed has `hello` deployed to the operator's user account.

Caveats:
- The exact naming has a bit of room for improvement, and may have diverged from the design document
- The test is not as pedantically type safe as it could be, since we simply use `types.raw` for resources such as NixOS users settings which *could* be more finely delineated

modelify
matches the name of `shell` to `operator-environment`.
this is a cop-out possible until
fricklerhandwerk/Fediversity#15.
after that, this will require actually figuring out how to get `options`
for `deployment.nix` - which may need `evalModules` with
`data-model.nix`.
