Implements the model-B2 membership authority (ratified compliance auth design) and inbound token verification.
- GET /v1/users/{id}/memberships: Keycloak supplies user->tenant links + org_roles (attribute projection until the realm migrates to Organizations); registered tenants override status/plan/products from registry tables (source: registry|keycloak). Closes the M5.2-deferred org_roles stub.
- New internal/authn: OIDC discovery + JWKS verification (go-oidc/v3), audience tenant-registry. /healthz + /readyz stay PUBLIC_EXPLICIT; all other routes INTERNAL_SERVICE_ONLY. AUTH_ENABLED=true refuses to start on incomplete config (fail-closed); false (dev default) keeps current behavior.
- Full suite green incl. postgres testcontainers; openapi.yaml updated (contract test passes).
Activation is a separate step (Auth-5): requires the orca-infra env merge and a portal service token (portal currently calls with no auth).
