feat: Implement job abandonment logic for reconnected workers in bot services. Introduce a mechanism to cancel pending and running jobs when a worker reconnects, ensuring a fresh start for new jobs. Update tests to verify job cancellation behavior upon worker re-registration. Enhance UI components in desktop application for better user experience and clarity on bot status.
