Run all frontend tests in CI with NixOS VM

[jmoggr]

This creates:

• a new Nix package which is responsible for running the vitest tests from the frontend package.
• a new Nix check, which is a full catcolab host running in a VM that we run the frontend tests against.

This result is end-to-end tests against a host that was setup from scratch.

I needed to bump the vitest version and some follow on dependencies to let vitest run in a read-only environment.

Thanks Jason, it will be great to run the full test suite in CI. Two questions/comments below.

Hi Jason, I tried reverting the changes to the pnpm lock file caused by accidentally adding jsdom and now I'm getting a hash mismatch that I can't figure out how to fix. Can you fix this and also remind me what I should do in the future?

I pushed a fix.

Steps:

• Comment out hash in frontend/default.nix
• run nix build .#frontend, it'll spit out an error like:

error: hash mismatch in fixed-output derivation '/nix/store/x9c0r42gkz8kb916l636mvpbci2wf9bs-frontend-pnpm-deps.drv':
         specified: sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
            got:    sha256-FqjdtE/OgmV+aYGh1AijQqvfg9/UQC/dClJRTLyGxCE=

• replace the old hash with the got hash.

I'll make sure to improve the docs on this

It's possible that there was another instance of something changing and the hash not getting updated. Fortunately this PR should prevent that going forward.
