feat: Update all production configs for dedicated PostgreSQL server

- PostgreSQL now on dedicated server: 10.0.0.207:5432
- Database: parentflow (user: postgres, password: a3ppq)
- Removed PostgreSQL from docker-compose.production.yml
- Updated start-production.sh to check PostgreSQL connectivity
- Updated migration scripts to use dedicated server
- Created .env.admin.example for admin service configuration
- Updated admin dashboard docs with PostgreSQL details
- Redis, MongoDB, MinIO remain as Docker containers on 10.0.0.240

Infrastructure:
- Application Server: 10.0.0.240 (PM2 + Docker services)
- Database Server: 10.0.0.207 (PostgreSQL only)
- Admin Server: 10.0.0.241 (future deployment)
- Nginx Proxy: Separate server with SSL configured
