- Updated SQL query in `EnvelopeReceiverAddReadSQL.cs` to select specific columns (`ENVELOPE_ID` and `RECEIVER_ID`) for improved performance and clarity.
- Changed mapping of `SentRecipients` in `EnvelopeReceiverController.cs` to expect a single `ReceiverReadDto` instead of a collection, reflecting a change in data handling.
- Modified `QueryAsync` in `EnvelopeReceiverExecutor.cs` to remove the generic type parameter, allowing for more flexible data handling.
