feat: add hide/show filter buttons for User mode in material validation

Add two buttons (隐藏勾选/显示全部) on the right side of the result
table for non-admin users to hide checked items or show all items.
- Buttons are disabled until validation completes
- Hidden items are tracked and can be restored
- Admin users see the original layout without these buttons
