fix(sdk): handle api error response code correctly and improve missing token hints

- Fixed an issue where the request function silently resolved on HTTP 200 even when the JSON body contained an API error (e.g. code 401). Now explicitly throws when code != 200.
- Improved error messages when OpenAPI or Notify tokens are completely missing, explicitly instructing the user to configure them in the panel.
