Implement progress tracking and status updates in Dashboard GUI processing

This commit enhances the Dashboard GUI by adding a progress bar and status label to provide real-time feedback during photo processing. The processing button is now disabled during the operation, and the progress updates are simulated to reflect various stages of the process. Additionally, error handling has been improved to reset the progress state in case of failures, ensuring a smoother user experience. The README has been updated to include these new features, emphasizing the improved interactivity and user feedback during processing tasks.
