Move Skip Data Folder to Experimental, editable backup items for Custom apps

- Moved 'Skip Data Folder' toggle from Config dialog to Settings > Experimental
- Custom apps now show all preset backup items as checkable options
- Users can check/uncheck backup items when editing Custom apps
- Added helper text when no items selected (only addon folders backed up)
- Removed skip_data_folder from per-app config (now global setting)
