Prereq for the wave-1 decommission. The cutover moved paperless+teslamate (postgres) and mealie (SQLite) to ringtail, but borgmatic and the Grafana TeslaMate datasource still pointed at the minikube copies — the migrated live data was unbacked since cutover, and dropping the minikube DBs would break the TeslaMate dashboards.
- Tailscale Service `blumeops-pg-ringtail` + Caddy L4 route `pg.ops.eblu.me:5434`
- borgmatic: teslamate + paperless postgres → :5434; mealie SQLite → ssh:eblume@ringtail
- Grafana TeslaMate datasource → pg.ops.eblu.me:5434
Deploy: sync databases-ringtail (tailscale svc) + grafana from branch; provision-indri --tags caddy,borgmatic; verify a backup run + dashboards. Unblocks the decommission PR.

## Summary
- Move hardcoded image tags to kustomization.yaml `images:` transformer across **22 services** — image names in manifests become version-agnostic templates, with tags centralized in one place per service
- Replace hand-written ConfigMap manifests with `configMapGenerator:` in **12 services** — config data extracted to standalone files, generated ConfigMaps include content hashes that trigger automatic pod rollouts on changes
- Create new `kustomization.yaml` for **forgejo-runner** and **nvidia-device-plugin** (switches ArgoCD from directory mode to kustomize mode, rendered output identical)
### Services modified
**Images only (8):** cv, devpi, docs, kube-state-metrics, miniflux, navidrome, teslamate, torrent
**Images + configMapGenerator (10):** alloy-k8s, forgejo-runner, frigate, grafana, homepage, kiwix, loki, mosquitto, ntfy, prometheus
**Images only, no configMapGenerator (4):** authentik (skip blueprints — special YAML tags), tailscale-operator-base (Deployment only, CRD image fields left as-is)
**Skipped entirely (6):** argocd (remote upstream), databases (no image fields), external-secrets, grafana-config (cross-kustomization dashboards), immich (Helm-managed), 1password-connect/cloudnative-pg (no kustomization.yaml)
### What changes at deploy time
- **images:** — no functional diff, `kustomize build` produces identical output with tags
- **configMapGenerator:** — ConfigMap names gain hash suffixes (e.g., `prometheus-config` → `prometheus-config-6f42fhctcb`) and all Deployment/StatefulSet/DaemonSet references are updated automatically. Pods will restart once per service on first sync due to the name change
## Test plan
- [x] `kubectl kustomize` builds all 30 service directories successfully
- [x] Image tags verified in rendered output for all modified services
- [x] ConfigMap hash suffixes verified in rendered output
- [x] ConfigMap references in Deployments/StatefulSets confirmed to use hashed names
- [x] All pre-commit hooks pass (yamllint, shellcheck, prettier, etc.)
- [ ] `argocd app diff` each service to confirm only expected ConfigMap name changes
- [ ] Deploy from branch starting with a low-risk service (e.g., mosquitto)
