- Updated `EnvelopeGenerator.Application.csproj` to include `Microsoft.Data.SqlClient` package.
- Refactored `CreateEnvelopeReceiverCommand` to inherit from `CreateEnvelopeCommand`.
- Enhanced `CreateEnvelopeSQL` with a SQL script for envelope creation.
- Introduced `CreateEnvelopeCommand` to encapsulate envelope creation data.
- Added `CreateEnvelopeCommandHandler` to process commands and interact with the database.
- Created `CreateEnvelopeResponse` class for handling responses from envelope creation.
Updated `CreateEnvelopeReceiverCommand` to use new types for `Document` and `Receivers`. Renamed `ReceiverGetOrCreateDto` to `ReceiverGetOrCreateCommand` and `DocumentCreateDto` to `DocumentCreateCommand` to align with the new command structure. Properties within these records remain unchanged.
Removed unnecessary parameters from CreateEnvelopeReceiverCommand, simplifying envelope creation. Updated EnvelopeReceiverController to reflect these changes by removing related fields from the JSON response, focusing on essential information.
Removed `CreateEnvelopeCommand` and introduced `CreateEnvelopeReceiverCommand` with updated parameters. Updated `ReceiverGetOrCreateDto` to include a new `Salution` parameter. Added XML documentation for the new command and associated DTOs.
