instances.nix-container-builder becomes nix_container_builder so
the service unit is gitea-runner-nix_container_builder.service
instead of gitea-runner-nix\x2dcontainer\x2dbuilder.service.

Remove the DinD-based k8s runner and add a native systemd Forgejo
Actions runner on ringtail for building containers with nix build
and pushing via skopeo. The runner uses the NixOS
services.gitea-actions-runner module with host execution (no
containers), and Ansible provisions the registration token from
1Password. Adds a new build-container-nix workflow for -nix- tags
and updates mise tasks to support both Dockerfile and Nix builds.

Enable k3s single-node server on ringtail (NixOS) for native amd64
container builds. Includes ArgoCD Application and manifests for a
Forgejo Actions runner with the `k8s-amd64` label, Ansible bootstrap
tasks for k3s token and runner secret, and containerd registry mirrors
pulling through Zot on indri.
