feat(controller): add GetAllAsync endpoint to HistoryController

- Added a new `GetAllAsync` method to HistoryController to retrieve envelope histories.
- Included query parameters for filtering by envelopeId, userReference, referenceType, status, and boolean flags for sender and receiver.
- Implemented validation of `referenceType` with `ReferenceType` enum, throwing an error for invalid values.
