refactor(DraggableList): simplify cursor styles and enhance drag handle visibility

- Removed unnecessary cursor styles from draggable items in the VirtualRow component.
- Updated snapshot tests to reflect changes in cursor styles.
- Introduced a new DragHandle component in ProviderSettings for improved drag interaction, with hover effects to enhance user experience.
