unkin-agent b355d6aafb mediamark: deploy the media marking app (#441)
## Why

mediamark needs a home in the cluster: it marks/organises media on the shared mediastore tree and drives the adult-tier sonarr/radarr through arrproxy's hash routes. This adds the full app to the `media` project, mirroring the watchstate two-host oauth2-proxy pattern and the arrstack static-CephFS + projected-API-keys patterns.

## How

- Adds `apps/base/mediamark/`: namespace, VaultAuth (`k8s/au/syd1`, role `default`), three VaultStaticSecrets, static mediastore PV/PVC, the app Deployment, oauth2-proxy ConfigMap/Deployment, two Services, and internal + external Gateway/HTTPRoute pairs.
- Binds a dedicated static PV (`mediamark-mediastore`, own `volumeHandle`, `claimRef`-pinned) to the same CephFS mediastore subvolume arrstack/fafflix/cheeztv use, RWX 10Ti Retain, mounted at `/media`.
- Runs the app as 1000:1000 (deliberately not 65532) so it owns files on the shared media tree and hardlink/rename moves stay valid; read-only root filesystem, all caps dropped, no service-account token, `/livez` + `/readyz` probes.
- Projects the sonarr/radarr API keys as one file per app under `/etc/mediamark/keys`, mirroring arrproxy's keys projection, with reloader annotations on both secrets.
- Fronts both `mediamark.unkin.net` (traefik-external, reflected Let's Encrypt wildcard, no cert-manager annotations) and `mediamark.k8s.syd1.au.unkin.net` (traefik-internal, vault-issuer) with a single oauth2-proxy using a relative `/oauth2/callback` redirect; gated on `akP-mediamark-user` and passing identity to the app as `X-Forwarded-Groups` via `PASS_USER_HEADERS`.
- Appends `mediamark` to the `wildcard-unkin-net` Certificate's two reflector namespace lists, and registers the app in `argocd/applicationsets/media.yaml` + `argocd/projects/media.yaml` with a passthrough `apps/overlays/au-syd1/mediamark` overlay.

## Prerequisite seeds (Ben, before pods go Ready)

These KV paths must exist under `kv/kubernetes/namespace/mediamark/default/` — the `mediamark/default` templated policy already grants read, so no terraform-vault change is needed:

- `oauth-credentials` — needs `client_id` and `cookie_secret` added alongside the existing `client_secret` (Authentik mediamark provider; both absolute callback URIs registered there).
- `sonarr` — key `apitoken`.
- `radarr` — key `apitoken`.

## Validation

- `kustomize build --enable-helm apps/overlays/au-syd1/mediamark` (18 resources) and `.../cert-manager` both build.
- kubeconform clean on both touched overlays.
- `pre-commit run --all-files` passes.
