feat: restore Simple/Baby Teeth EXT combos, hide from PreAuth only

- Restore simpleExtraction (D7140), surgicalExtraction (D7210), babyTeethExtraction (D7111)
- Add excludeIds prop to RegularComboButtons for per-button filtering
- PreAuth tab excludes Simple EXT and Baby Teeth EXT; Insurance Claim tab shows all
