The token-attachment bug (secureRoutes set to the app origin, which a relative
api-client URL never matches) was only caught by the full-stack e2e. Add a fast
unit guard: drive the REAL angular-auth-oidc-client interceptor and the REAL
api-client against the production route value, faking only the config source and
the token storage. Asserts the bearer token rides the relative /self-service/
call and is withheld from the anonymous /openbaar/ call.
Extract the value to a shared SECURE_API_ROUTES constant so the test binds to
exactly what the app configures. Verified the guard fails (Authorization null)
if the value regresses to an origin.
