Modified the `ReferenceType` enum in `Constants.vb` to change the values for `Sender` and `Receiver`. Removed the `ReferenceType` and `StatusName` properties from `EnvelopeHistory.cs`. Updated status code comments in `HistoryController.cs`, adding new codes for `EnvelopeRejected` and `EnvelopeWithdrawn`, and adjusted parameter descriptions to align with the new enum values.
