Refactor queue management by removing deprecated components and updating configuration

- Removed the QueueConfig structure and related queue management files as they are no longer in use.
- Updated the worker initialization to reflect the removal of queue-related configurations.
- Cleaned up the bootstrap process by eliminating deprecated logging related to the queue system.

This update streamlines the worker's configuration and prepares the codebase for future enhancements without the legacy queue management components.
