Refactor constants and update CreateHistoryCommand

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.
