Updated `EnvelopeHistoryQuery` and `ReadEnvelopeHistoryQuery` to include a new optional `OnlyLast` parameter, removing the `Status` parameter. Documentation comments have been revised to reflect these changes, including updates in the `HistoryController` class.
Updated EnvelopeHistoryQuery to include a new `Status` parameter for describing the envelope's status. Modified the `ReferenceType` property to return `ReferenceType.System` when neither the envelope's `User` nor the `Receiver` is defined.
Updated ReadEnvelopeHistoryQuery to include the `Status` parameter and set default values of `null` for `Envelope` and `Receiver`, ensuring consistency with the base class.
- Introduced a new `UserQuery` record to encapsulate user-related information, replacing individual fields in `EnvelopeQuery`.
- Added a `ReferenceType` property in `EnvelopeHistoryQuery` to enhance reference handling logic.
- Modified `EnvelopeQuery` to use the new `UserQuery` structure, simplifying the data model.
- Updated `HistoryController` with a new constructor and restructured the `GetReferenceTypes` method.
- Introduced `ReadEnvelopeHistoryQuery` to allow for more specific envelope history queries.
- Overall improvements enhance code structure, clarity, and querying capabilities.
