feat: disable/enable all clips in a subcategory folder at once

- Sub menu now has per-folder "Disable all" / "Enable all" buttons with live counts
- relocate_video_clips accepts filename=None to move every video's clips in a folder
- get_all_folder_counts returns profile-wide per-folder counts (incl _disabled)
- Disable-all confirms before moving; both refresh markers + playlist counts
