Refactor compaction logic and update test configurations
- Refactored `merge_all_runs` function to use `sort_ranged_items` for sorting.
- Improved item merging logic by iterating with `into_iter` and handling overlaps.
- Updated test configurations to use `max_active_window_runs` instead of `max_active_window_files` for consistency.
