Centralized `HttpRequestException` creation with a new `CreateHttpException` method to improve code reuse and consistency. Updated methods to handle `HttpStatusCode.NotFound` gracefully, returning `null` where appropriate instead of throwing exceptions. Introduced `TryGetSenderDocumentBytesByEnvelopeIdAsync` to encapsulate fallback logic for fetching document bytes. Removed redundant inline exception handling and standardized error handling across methods.
