feat: replace static examples with live preview in display options

Update ConfigPanel to show live preview alongside checkboxes instead
of pre-generated static examples.

- Remove displayExamples prop and static example SVGs
- Add 2-column grid layout: checkboxes left, live preview right
- Replace CheckboxWithExample with simple checkboxes
- Update AdditionWorksheetClient to remove example generation
- Update page.tsx to remove displayExamples prop passing

Users now see real-time preview of their display option selections
using the exact same rendering code as the final worksheet.
