Fix todo deletion not refreshing milestone widgets and file watcher race condition

- Add _load_milestones() call after _load_todos() in _on_todo_deleted and
  _on_todo_edited to refresh milestone widgets showing linked todos
- Replace boolean _ignoring_file_change flag with timestamp-based ignore
  window (0.5s) to handle multiple file system events from a single save
- Add _is_within_save_window() helper method for cleaner event filtering
