Add help search endpoint to system controller and define HelpSearchRequestJson model

- Introduced a new POST endpoint `/help-search` in the system controller to facilitate help center searches while avoiding CORS issues.
- Added HelpSearchRequestJson model to handle the request structure for help searches.
- Implemented logic to validate authorization tokens and manage requests to the help center API, including error handling for failed requests.
