Add "Clear History" Option for Completed Jobs in the Queue

This feature proposes adding a "Clear History" function that allows users to remove only completed jobs from the processing queue. Currently, managing the queue can be cumbersome, and having the ability to selectively clear completed jobs would streamline workflow management.

Implementing this option would enable users to maintain a cleaner and more organized queue, making it easier to focus on ongoing tasks and improving overall efficiency. This targeted clearing of completed jobs would enhance user experience by reducing clutter while retaining visibility of pending or in-progress tasks.
