Add production deployment scripts and quickstart guide

- Add deploy-to-vm.sh script for easy VM deployment
- Add systemd service file template
- Add Nginx configuration with SSL and rate limiting
- Add DEPLOYMENT_QUICKSTART.md for n8ndocumentation.aiservices.pl
- Update REMOTE_DEPLOYMENT.md to reference quickstart

The deployment process is now streamlined:
1. Copy .env.example to .env
2. Configure for production (domain, auth token)
3. Run ./scripts/deploy-to-vm.sh

Tested locally with production configuration - all endpoints
working correctly with authentication.
