This commit replaces the `AddEnvelopeGeneratorRepositories` method with `AddEnvelopeGeneratorInfrastructureServices`, allowing for more flexible configuration through `IConfiguration` and `Action<SQLExecutorParams>`. The `SQLExecutor` class now utilizes `SQLExecutorParams` for its connection string, enhancing configurability. A new `SQLExecutorParams` class has been introduced to encapsulate connection string management. Various service registration calls have been updated to integrate the new infrastructure services, improving modularity and ease of database connection management.
- Updated `ISQLExecutor<TEntity>` to inherit from new `ISQLExecutor` interface for improved SQL execution flexibility.
- Added package references for `Dapper` and `DigitalData.Core` in project files.
- Modified `CreateEnvelopeCommand` to include `[BindNever]` on `UserId` for better model binding control.
- Refactored `CreateEnvelopeCommandHandler` to use `DynamicParameters` for SQL parameter handling.
- Updated `CreateEnvelopeSQL` to select only the top record for performance.
- Introduced `GetIdOrDefault` method in `ControllerExtensions` for user ID retrieval with fallback.
- Added `CreateAsync` method in `EnvelopeController` for envelope creation using `IMediator`.
- Ensured infrastructure project has necessary package references.
- Refactored `SQLExecutor` to implement new interface and simplified constructor.
- Introduced `SQLExecutorBaseEntity` for entity-specific SQL command execution.
