Remove nixpkgs version fallback and delete nettest container

Nix builds now require an explicit version = "..." in default.nix —
no implicit nixpkgs eval fallback. Also removes nettest (outgrown)
and updates all doc/task references.

Discovered during analysis of [[adopt-commit-based-container-tags]]: nix containers (authentik, ntfy, nettest) derive their bundled app version from the nixpkgs pin, not from an explicit declaration.

Currently, nix containers can only be built on ringtail (the `nix-container-builder` runner). There is no local build path for developers — the only option is to push and wait for CI. Adding a Dagger-based nix build gives both local evaluation and version extraction.
