feat(infrastructure): refactor DIExtensions for DbContext registration

* Removed `dbContextOptions` parameter from `AddEnvelopeGeneratorInfrastructureServices`
* Moved `AddDbContext` registration into `Config` class with overloads for both `Action<DbContextOptionsBuilder>` and `Action<IServiceProvider, DbContextOptionsBuilder>`
* Simplified service registration flow and improved extensibility
