feat(db): add Prisma schema with all models

Configure Prisma ORM with PostgreSQL database schema including:
- Organization, Site, Court models for multi-tenancy
- User with role-based access and Client for customers
- Booking and Payment models for reservations
- MembershipPlan and Membership for subscriptions
- Product, Sale, SaleItem, CashRegister for POS
- Tournament, TournamentInscription, Match for competitions
- All necessary enums, relations, indexes, and cascading deletes
- Prisma client singleton for Next.js
