Improved memory management by using a weak reference for the Timer to prevent potential retain cycles.
Refactored repeated cell configuration logic into a helper function to improve code readability and maintainability.
Optimized UI updates to avoid unnecessary progress view updates, enhancing performance.
Ensured proper invalidation of the timer to prevent it from running in the background when not needed.
No changes to external behavior or API; the functionality remains consistent with the original implementation.
