Fix job progress display issue

- Fixed backend get_progress handler to use queue ID instead of cluster job ID
- Removed duplicate get_progress handler that was causing confusion
- Progress is now correctly retrieved from the processing_queue table using the queue ID

This resolves the issue where job progress was always showing 'Processing...' instead of actual progress status and advancement bar.
