tenant-registry's API is INTERNAL_SERVICE_ONLY — once its AUTH_ENABLED flips, every route but /healthz and /readyz needs a Keycloak token whose audience contains tenant-registry. Today the portal calls it with no Authorization header at all, so this is the prerequisite for enabling enforcement there.

The portal calls tenant-registry as a service principal (machine-to-machine), which is distinct from the visitor's SSO session that authenticates a human against dev-portal.

New src/lib/service-token.ts: fetches and caches a client_credentials token for the realm's new portal-svc client, refreshes 30s before the 5-minute expiry, and de-dupes concurrent fetches so parallel renders share one request. A failed request throws rather than silently making an unauthenticated call, and does not poison the cache.
Wired into the single req() choke point in tenant-registry.ts, so all 10 call sites are covered at once.
Inert until configured: with PORTAL_SVC_CLIENT_ID / PORTAL_SVC_CLIENT_SECRET unset the helper returns null and no header is sent — exactly today's behaviour. That is what makes it safe to deploy before tenant-registry enforces.

Realm side is already done: portal-svc client created with the tenant-registry-audience scope; a live token was verified to carry aud: [tenant-registry, account] with a 300s TTL. Env staged in sharang/orca-infra#56 (secret already set via orca secrets).

9 new tests; full suite 79 green; typecheck, lint (--max-warnings 0) and production build all clean.

tenant-registry's API is INTERNAL_SERVICE_ONLY: once its AUTH_ENABLED
flips, every route but /healthz and /readyz requires a Keycloak token
whose audience contains `tenant-registry`. The portal calls it as a
service principal — machine-to-machine, distinct from the visitor's SSO
session, which authenticates a human against dev-portal.

New src/lib/service-token.ts fetches and caches a client_credentials
token for the realm's portal-svc client, refreshing 30s before the
5-minute expiry and de-duping concurrent fetches so parallel renders
share one request. A failed request throws rather than silently falling
back to an unauthenticated call, and does not poison the cache.

Wired into the single req() choke point in tenant-registry.ts, so every
call is covered. Inert until configured: with PORTAL_SVC_CLIENT_ID /
PORTAL_SVC_CLIENT_SECRET unset the helper returns null, no header is
sent, and behaviour is exactly as today — which is what keeps this
deployable before tenant-registry starts enforcing.

9 new tests; full suite 79 green; typecheck, lint and build clean.
