Refactor services to remove ApiOptions dependency

Simplified `DocReceiverElementService` and `EnvelopeService` by removing the `ApiOptions` dependency. Updated constructors to eliminate the `IOptions<ApiOptions>` parameter and switched to using relative URLs directly for API requests.

Removed unused `BaseUrl` and `UsePredefinedReports` properties from `ApiOptions`. Cleaned up redundant fields, constructor logic, and unused `using` directives in affected services.

Registered `EnvelopeService` in `Program.cs` with `AddScoped`. These changes improve maintainability, reduce configuration overhead, and make the services more self-contained.
