Recurring review sweep: 4 doc cards + nvidia-device-plugin v0.19.2 (#366)

Knocks out the two daily recurring review tasks (doc review + service review) in one PR.

## Doc review (4 never-reviewed reference cards, `last-reviewed: 2026-06-04`)
- **cluster.md** — Kubernetes version v1.34.0 → **v1.35.0**; refreshed the stale ringtail workload list and noted the in-progress minikube→k3s migration (points to `[[ringtail]]` as the canonical list).
- **ntfy.md / tempo.md / alloy.md** — corrected image references: these are now **locally-built `registry.ops.eblu.me/blumeops/*` nix containers** (ntfy v2.19.2, tempo v2.10.3, alloy-k8s v1.16.0), not upstream Docker Hub. Fly.io alloy binary bumped to v1.16.1.

## Service review
- **nvidia-device-plugin** (ringtail GPU): v0.19.0 → **v0.19.2**. Upstream patch releases — CDI/Tegra fixes + dependency bumps, no breaking changes for our manifest-based CDI + RuntimeClass setup (the service-account change in the notes is helm-only).

## Not in this PR (need container rebuilds, deferred)
The other stale services are locally-built nix images, so upgrading them is a forge-runner rebuild rather than a clean tag bump — left untouched (not date-bumped, so they resurface): **prometheus** (v3.10.0→v3.12.0), **loki** (3.6.7→3.7.2), **kube-state-metrics**, **homepage**. Happy to do these as a follow-up rebuild PR.

## Deploy / verify
Not yet deployed — `nvidia-device-plugin` still points at `main`. After review:
```
argocd app set nvidia-device-plugin --revision reviews-jun4 && argocd app sync nvidia-device-plugin
# after merge:
argocd app set nvidia-device-plugin --revision main && argocd app sync nvidia-device-plugin
```
