Erich Blume a18a424866 Pin NixOS service versions via nixpkgs-services overlay (#321)
## Summary

- Add `nixpkgs-services` flake input pinned to a specific nixpkgs commit, with an overlay that pulls `forgejo-runner`, `snowflake`, and `k3s` from it instead of the rolling `nixpkgs`
- Dagger `flake-update` pipeline now excludes `nixpkgs-services` via `--exclude`
- Fix stale nix-container-builder version in service-versions.yaml (was 12.6.4, actually running 12.7.2)
- Add k3s and minikube to service-versions.yaml tracking
- Document the pinning approach in review-services how-to and ringtail reference

## Motivation

During service review, discovered that flake updates had silently upgraded forgejo-runner from 12.6.4 → 12.7.2 without updating service-versions.yaml. This "sneak-in upgrade" bypasses the service review process. The overlay ensures these three services only change versions deliberately.

## Test plan

- [ ] Verify `nix flake update` from `nixos/ringtail/` does not change `nixpkgs-services` lock entry
- [ ] Verify `mise run provision-ringtail` builds successfully with the overlay
- [ ] Confirm running service versions unchanged after deploy
