- Add prisma seed to initialize core system accounts (HQ, OP, FEE) and pool accounts
- Auto-create province/city system accounts on-demand during contribution distribution
- Province/city regions are also auto-created if not exist
This ensures:
1. Core accounts exist after deployment (via seed)
2. Province/city accounts are created dynamically as orders come in
