- Updated `BaseController.vb` to use `Receiver.Id` for deletion.
- Changed `Receivers` property in `frmEnvelopeEditor.vb` to `BindingList(Of ReceiverVM)` and adjusted initialization and usage throughout the file.
- Modified `frmFieldEditor.vb` to use `List(Of ReceiverVM)` for receivers and updated related methods.
- Adjusted color assignment logic in `frmMain.vb` to utilize a new `Value` class.
- Added new project for `EnvelopeGenerator.Form` in the solution file.
- Introduced new enums `ContractType` and `PageOrientation` in their respective files.
Updated `CreateHistoryCommand.cs` to use the `EnvelopeStatus` enum directly from the `EnvelopeGenerator.Domain.Constants` namespace. Refactored `Constants.cs` to consolidate multiple enums related to statuses, types, and roles. Modified `Fake.cs` to align with the new enum structure and introduced `Value.cs` for better organization of constant string values. Overall, these changes enhance code clarity and maintainability.
