Introduced a new `DocumentService` class to handle fetching PDF document bytes from an API endpoint. The service uses `HttpClient` for HTTP communication and `IOptions<ApiOptions>` for accessing API configuration. Added the `GetDocumentAsync` method to perform the HTTP GET request, handle responses, and return the document bytes along with the HTTP status code. Included necessary `using` directives and encapsulated the service in the `EnvelopeGenerator.ReceiverUI.Services` namespace.
