GET /v1/users/{id}/memberships answers 'which tenants does this JWT
subject belong to, with which org_roles and entitlements' (ratified
auth design, model B2). Keycloak supplies user->tenant links and roles
via the Adapter (attribute projection until the realm migrates to
Organizations); registered tenants override status/plan/products from
registry tables.
New internal/authn verifies Keycloak bearer tokens (OIDC discovery +
JWKS, audience AUTH_EXPECTED_AUDIENCE, default tenant-registry). With
AUTH_ENABLED=true all routes except /healthz + /readyz require a token
and the server refuses to start if the verifier cannot initialize;
false (dev default) keeps the API open. Completes the M5.2-deferred
org_roles lookup and replaces the 'M4.3 adds JWT validation' TODO in
the spec.
