Sync point-size to config immediately

Remove debounced/pending write machinery and write point-size to config immediately when committing. Deleted the QTimer, _pending_config_point_size_write attribute, and _flush_pending_point_size_config_write method. _commit_active_points_size_to_config now calls save_point_size_to_config directly, reports success via viewer.status, and logs failures; related scheduling code in the size setter was removed. This simplifies point-size persistence and improves error handling.
