Examples: Orchestration Refactoring (#2686)

* feat(dispatcher): add production mode support for error handling and extend URI validation tests

- Introduced `productionRouter` in `DummyTestRouter` to enable production mode configuration.
- Updated `DispatchingInterceptor` to adjust error messages in production mode.
- Expanded `DispatchingInterceptorTest` with production-specific URI validation.

* refactor(tests): update test method names and improve flow structure in `CallAuthenticationExampleTest`
