feat: add NIP-99/Gamma Markets kind categories for curating mode

Add marketplace_nip99 category with Plebeian Market event kinds:
- 30402 (Products)
- 30403 (Orders - legacy)
- 30405 (Collections)
- 30406 (Shipping options)
- 31555 (Product reviews)

Add order_communication category for Gamma Markets (kinds 16, 17).

Rename existing marketplace category to marketplace_nip15 for clarity
while keeping backward compatibility with the legacy alias.
