REFACTOR - Improvements for the /requests/{object_id}/update_status endpoint

[MonikaVo]

• The object_id in the URL is currently not forwarded to the endpoint and therefore, the object_id needs to be provided separately during the process. The data parameter in the curl command is empty, which appears unusual for an endpoint of type POST.
• The "" character at the end of the endpoint seems unnecessary.
• It is declared as a POST method, but it does not post anything to FINALES. Consider defning it as GET or add data to the call to this endpoint.

(This is based on some feedback we got and I hope, I correctly forwarded it.)
