Adds the arrproxy front door to the arrstack app: the external, oauth-gated entry to sonarr/radarr/prowlarr with per-user API-key brokering, wired to match the arrproxy v0.1.0 code (ports, routes, identity headers, keys dir). Topology (apps/base/arrstack/arrproxy): - oauth2-proxy Deployment/Service is the single front (Authentik OIDC), path- routing via --upstreams to arrproxy-ui (/, static SPA) and arrproxy-api (/api token API + /<app> proxy). skip-auth-regex ^/[^/]+/api bypasses auth only for the *arr proxy API (/sonarr/api...), keeping /api/tokens + /api/me and the UI authenticated. - Identity+groups reach the api via --pass-user-headers (X-Forwarded-*); the api reads ARRPROXY_GROUPS_HEADER=X-Forwarded-Groups (set-xauthrequest is auth_request-response-only and never reaches an upstream). - oauth2-proxy trusts identity.unkin.net's internal-CA cert via a combine-certs initContainer (system roots + vault-ca-cert). - CNPG token store (arrproxy-db, 2 instances, cephrgw backups); a wave-1 Sync hook Job applies the schema (arrproxy-api does not self-migrate). - VaultStaticSecrets for the seeded ARRPROXY_PEPPER and the oauth-credentials; the real *arr keys reuse the existing <app>-apikey Secrets (projected one file per app into /etc/arrproxy/keys). - External Gateway (traefik-external, arrstack.unkin.net, vault-issuer TLS) + HTTPRoute to the oauth2-proxy entry. Also adds the arrstack.unkin.net apex A record (-> external DMZ VIP 198.18.199.0) to the bind-operator unkin.net zone.
