Refactor: Replace EmailSenderWorker with AsyncIniteWorker

Removed EmailSenderWorker and its configuration, including
EmailSenderWorkerConfiguration. Introduced AsyncIniteWorker
as a replacement, simplifying the design by removing
configuration-based toggling.

- Deleted EmailSenderWorkerConfiguration.cs.
- Removed EmailSenderWorker and its registration from Program.cs.
- Registered AsyncIniteWorker in DependencyInjection.cs.
- Renamed and refactored EmailSenderWorker to AsyncIniteWorker.
- Updated namespace and removed unused configuration dependencies.
