Simplify FinalizeDocumentJob execution by removing Quartz dependencies and the IFinalizeDocumentJobRunner abstraction. The job now uses an ExecuteAsync method with direct access to configuration and options via dependency injection. Worker is updated to call the job directly, and service registration is streamlined. This improves clarity and integration with .NET DI.
Refactored Worker to accept IConfiguration and read the delay interval from "Worker:DelayMilliseconds" in appsettings.json, replacing the previously hardcoded value. This allows the worker execution interval to be configured without code changes. Added a minimum delay safeguard and updated appsettings.json accordingly.
Added a Worker class in EnvelopeGenerator.ServiceHost that logs an informational message every second. Registered the Worker as a hosted service in Program.cs to run alongside the web API.
