fix: pass through upstream HTTP status codes from /article

- Non-2xx responses (404, 429, 5xx) are now forwarded to the
  client with their original status code and response body
- Increased WriteTimeout to 45s to accommodate slow upstream API
- Added explicit resp.Body.Close() and response flush before return
