refactor: Move Prisma schema to /dbal/shared (source of truth)

The Prisma schema is the single source of truth for the entire system
and should live in shared, not in development-specific location.

MOVED:
- /dbal/development/prisma/schema.prisma → /dbal/shared/prisma/schema.prisma

UPDATED:
- DBAL package.json: db:* scripts reference ../shared/prisma/schema.prisma
- config package.json: schema reference updated
- gen_prisma_schema.js: outputs to shared location

STRUCTURE NOW:
- /dbal/shared/prisma/ - Prisma schema (source of truth)
- /dbal/shared/seeds/ - Seed data (YAML files)
- /dbal/development/ - Uses shared schema via relative path

This ensures:
✅ Single source of truth for schema
✅ Schema is shared across all implementations (Phase 2 TypeScript, Phase 3 C++)
✅ Development just references the shared schema
✅ Independent deployability maintained
