revert: restore app/appType param compatibility and revert segmented-thumb pointer-events change

- Restore backend commands to accept app_type/app/appType with priority app_type
- Frontend invoke() now passes both { app_type, app } again
- Revert CSS change that set pointer-events: none on segmented-thumb
- Keep minor fix: open_config_folder signature uses handle + respects both names

Note: warnings for non_snake_case (appType) are expected for compatibility.
