rke2's `registries.yaml` already rewrites upstream image names to the artifactapi mirror, so manifests must carry canonical upstream names. Only in-house `artifactapi.k8s.syd1.au.unkin.net/docker-internal/...` images stay explicit.
Changes:
- Point the arrproxy migrate job at `docker.io/library/postgres:18-alpine`.
- Point the arrproxy oauth2-proxy cert-combine init container at `docker.io/library/alpine:3`.
- Point the arrstack ValkeyCluster at `docker.io/valkey/valkey:9.0.0`.
Tags are unchanged. `kustomize build --enable-helm apps/overlays/au-syd1/arrstack` differs from main only in those three image strings. No extra proxied refs found in these files (the oauth2-proxy image itself is already canonical `quay.io/...`).

Repoints the arrproxy `oauth2-proxy` sidecar image to the real upstream address `quay.io/oauth2-proxy/oauth2-proxy:v7.15.3`, replacing the one-off artifactapi copy (`artifactapi.k8s.syd1.au.unkin.net/ghcr/oauth2-proxy/oauth2-proxy:v7.15.3`).
## Why
Pull the image from its canonical upstream location instead of a hand-copied artifactapi path. containerd on rke2 transparently mirrors `quay.io` through artifactapi, so the real address resolves without hardcoding the proxy host.
## Change
- `apps/base/arrstack/arrproxy/oauth2-proxy-deployment.yaml`: image only -> `quay.io/oauth2-proxy/oauth2-proxy:v7.15.3`.
Validated with `kustomize build --enable-helm apps/overlays/au-syd1/arrstack` and pre-commit.
## Dependencies (must be in place before merge)
1. **rke2 `registries.yaml` mirrors quay.io** — already configured in puppet (`hieradata/roles/infra/k8s.yaml`, `rke2::registries` rewrites `quay.io` -> `artifactapi.k8s.syd1.au.unkin.net/quay/$1`). No change needed.
2. **artifactapi quay remote allowlists oauth2-proxy** — terraform-artifactapi PR unkin/terraform-artifactapi#35 adds `^oauth2-proxy/` to the quay remote patterns. **This PR must NOT be merged until #35 is applied**, otherwise the caching proxy rejects `oauth2-proxy/*` and the sidecar fails to pull.

Deploys arrproxy v0.1.0 (task 9 final integration) into the existing `arrstack` app: the external, Authentik-gated front door for sonarr/radarr/prowlarr with per-user API-key brokering. Manifests are wired to match the arrproxy v0.1.0 code (ports, routes, identity headers, keys dir), mirroring the ghp/artifactapi estate patterns.
## Topology (`apps/base/arrstack/arrproxy/`)
- **oauth2-proxy** Deployment + Service `arrproxy` is the single front (OIDC against the Authentik `arrstack` app). It path-routes via `--upstreams` to:
- `arrproxy-ui` for `/` and static SPA assets,
- `arrproxy-api` for `/api/*` (token API) and `/sonarr|/radarr|/prowlarr` (the *arr proxy).
- `--skip-auth-regex=^/[^/]+/api` bypasses oauth **only** for the *arr proxy API (`/sonarr/api...`), while `/api/tokens`, `/api/me` and the UI stay authenticated.
- Identity+groups reach the api via `--pass-user-headers` (`X-Forwarded-{User,Email,Groups}`). The api reads `ARRPROXY_GROUPS_HEADER=X-Forwarded-Groups` — `--set-xauthrequest` only populates auth_request *response* headers and never reaches an `--upstreams` backend, so it is intentionally not used.
- oauth2-proxy trusts `identity.unkin.net` (internal Vault-PKI CA) via a `combine-certs` initContainer (system roots + `vault-ca-cert`), same pattern as artifactapi.
## Data + secrets
- **CNPG** token store `arrproxy-db` (2 instances, cephrgw S3 backups + nightly ScheduledBackup). arrproxy-api does **not** self-migrate, so a wave-1 ArgoCD `Sync` hook Job applies `migrations/0001_init.sql` (mirrored into a ConfigMap) as the CNPG app user. DSN built from the generated `arrproxy-db-app` Secret.
- **VaultStaticSecrets** (arrstack `default` SA / templated role — no terraform-vault change): `arrproxy-pepper` (seeded) and `oauth-credentials`. The three real *arr keys are **reused** from the existing `<app>-apikey` Secrets, projected one file per app into `/etc/arrproxy/keys`.
## Exposure
- **Gateway** `traefik-external`, hostname `arrstack.unkin.net`, cert-manager `vault-issuer` TLS (`arrproxy-gateway-tls`); HTTPRoute → the oauth2-proxy entry Service (+ HTTP→HTTPS redirect).
- Adds the `arrstack.unkin.net` apex A record → external DMZ VIP `198.18.199.0` to the bind-operator `unkin.net` zone (`apps/base/bind-internal/authoritative/records.yaml`), mirroring the ghp/identity apex records.
## Validation
- `kustomize build --enable-helm apps/overlays/au-syd1/arrstack` renders cleanly; `kubeconform` = 51/51 valid; `pre-commit` passes (no plain Secrets).
## Prerequisites / flags for end-to-end function (NOT in this PR)
- **(a)** Each *arr must run with `UrlBase=/<app>` (path-based hosting) — arrproxy preserves the `/<app>` prefix upstream.
- **(b)** The Authentik `arrstack` OIDC app (terraform-authentik PR #18) must be applied, with redirect URI `https://arrstack.unkin.net/oauth2/callback` registered and the `ak_groups` scope emitted. Confirm the discovery slug matches `OAUTH2_PROXY_OIDC_ISSUER_URL` (`https://identity.unkin.net/application/o/arrstack/`).
- **(c)** Browser XHR to `/<app>/api` is oauth-**bypassed** (skip-auth-regex), so the SPA-driven proxy calls that rely on the session (no per-user token) will not carry identity on that path — expected per the arrproxy trust model; token-based *arr clients are unaffected.
- **NetworkPolicy:** the arrproxy-api Service is not exposed via any HTTPRoute and the api strips forged identity headers in-code, but the README recommends a NetworkPolicy restricting api ingress to oauth2-proxy. The estate currently has **zero** NetworkPolicies, so one was not added here to avoid being the first (and risking probe breakage) before the CNI’s policy/probe behavior is confirmed — flagged as follow-up hardening.
- Please confirm: CNPG size (2 instances / 10Gi), backups on, hostname/VIP, and UI theme.
