- Removed `Sender` parameter and properties from `EnvelopeQuery`.
- Deleted `SenderQuery` class entirely.
- Cleaned up `HistoryQuery` by removing unused `using` directives and `ReferenceType` logic.
- Added `Related` parameter to `ReadHistoryQuery` for reference type indication.
- Updated `ReferenceType` enum in `Constants.vb` to use explicit integer values.
- Modified `HistoryController` to utilize the new `Related` property for determining sender/receiver inclusion.
Renamed `EnvelopeHistoryQuery` to `HistoryQuery` and
`ReadEnvelopeHistoryQuery` to `ReadHistoryQuery` to improve
clarity. Moved `StatusQuery` to the new
`EnvelopeGenerator.Application.Histories` namespace. Updated
`HistoryController` to use `ReadHistoryQuery`. Removed
unused `using` directives and added relevant ones to align
with the new structure. These changes enhance code
maintainability and organization.
