Introduced a new `AddReceiver` method in the `Extension` class to facilitate adding a receiver to an envelope. This method includes parameters for `envelope_uuid`, `emailAdress`, `salutation`, and an optional `phone`, along with XML documentation for clarity.
Removed the `EnvelopeReceiverCreateReadSQL` class and added the `EnvelopeReceiverAddReadSQL` class, which defines the SQL command for adding a receiver. The new class also includes XML documentation comments for better understanding.
This commit removes the IEnvelopeExecutor interface and its implementation, replacing it with ISQLExecutor. The CreateEnvelopeAsync method in Extension.cs now directly creates DynamicParameters. The CreateEnvelopeCommandHandler has been updated to utilize ISQLExecutor. Additionally, the EnvelopeExecutor class has been removed, and a new SQL command class, EnvelopeReceiverCreateReadSQL, has been added for managing envelope receiver SQL operations.
Added a new static class `Extension` in `Extension.cs` to encapsulate methods for creating parameters and asynchronous envelope creation. Removed previous implementations from `EnvelopeCreateReadSQL.cs` for better organization. Updated `using` directives in `CreateEnvelopeCommandHandler.cs` and `EnvelopeCreateReadSQL.cs` for consistency.
