Combined sender and receiver document retrieval into a single GetDocument endpoint. The endpoint now authorizes both Sender and Receiver.FullyAuth roles, handling their logic based on role detection. Sender requires a query parameter; receiver extracts envelope ID from claims and disallows query params. Updated method signature and endpoint documentation.
