feat: move layout controls to OrientationPanel with toggles

Move Problem Numbers and Cell Borders controls from standalone section
to OrientationPanel component as simple checkbox toggles. This groups
all layout-related options together in one place.

Changes:
- Add problemNumbers/cellBorders props to OrientationPanel
- Add Layout Options section as Row 3 with divider
- Use checkboxes for simple on/off control (not thermometers)
- Update AdditionWorksheetClient to pass displayRules props
