Simplified from over-engineered multi-card selection to two clean
variants based on funeral type:
- Service & Cremation: compact card + witness Yes/No (ToggleButtonGroup)
- Cremation Only: compact card + badge + "Included in Package" notice
Removed: multi-card grid, priority dropdown, special instructions,
crematoriums array prop. Crematorium is always pre-selected by provider.
