fix(dashboard): gate external-IPs services query on tenant namespace

Address review feedback from gemini-code-assist on ExternalIpsPage.tsx: add
enabled: !!tenantNamespace to the services useK8sList so it does not issue a
cluster-wide /api/v1/services request (403 for non-admin tenants) before the
tenant namespace is known.
