fix: Improve progress tracking and UI update efficiency in ProgressPage

- Modified the progress update logic to accept sub-percent values while ensuring monotonic progress.
- Introduced a throttling mechanism to limit UI updates, reducing potential performance issues from frequent progress changes.
- Enhanced reset and timer restart functions to invalidate the UI update timer appropriately.

These changes enhance the responsiveness and accuracy of the progress display, improving user experience during long-running tasks.
