$response = curl_exec($curl);

That base URL is incorrect. Account-d.docusign.com is only for authentication.
Requests should be made to {SERVER}/restapi/v2.1
So for you it would be demo.docusign.net/restapi/v2.1/accounts/{ACCOUNT_ID/envelopes
Here's the dev centre article showing the whole process
