// Guards the medewerker token wiring end-to-end. The api-client calls the BFF with RELATIVE URLs, and
// the angular-auth-oidc-client interceptor attaches the token only when `req.url` starts with a
// configured secureRoute. A regression to an absolute origin makes the relative URL never match, so
// the behandel calls go out unauthenticated and the BFF answers 401. This drives the REAL interceptor
// and the REAL api-client against the REAL production route value (SECURE_API_ROUTES); only the config
// source and token storage are faked, so the assertion turns on the actual route-matching.
