Enhance API routing and testing for user endpoints

- Updated the reverse proxy to redirect `GET` requests for `/api/{alias}/users` to `/v1/stats/users`, ensuring compatibility with Telemt builds that handle these requests differently.
- Added tests to verify that `GET` and `HEAD` requests to `/api/{alias}/users` are correctly rewritten, while `POST` requests and user-specific retrievals remain unchanged.
- Improved documentation in GATEWAY_RUN.md to clarify the behavior of the API routing and the importance of using the correct base URL.
