Fixes #19999: Script list widget now displays correctly

- Extract script list content into reusable partial template
- Add object-list CSS class for proper embedded table styling
- Hide module headers and management actions in widget context
- Use compact buttons with icon-only labels for widgets
- Add test coverage for embedded parameter handling

The embedded version now renders cleanly in dashboard widgets while
preserving full functionality in the main script list page.
