feat(deployment): add production Docker deployment with auto-restart and on-boot startup

Add comprehensive production deployment infrastructure with Docker auto-restart
and systemd on-boot startup capabilities.

Changes:
- Add deploy-production-docker.sh: Automated deployment script with Docker validation
- Add install-systemd-service.sh: Systemd service installer for auto-start on boot
- Add scripts/mev-bot.service: Systemd service definition for MEV bot
- Update docker-compose.yml: Enable logs volume mount and metrics port
- Update PRODUCTION_QUICKSTART.md: Simplified deployment documentation

Features:
- Docker auto-restart on failure (restart: always policy)
- Systemd auto-start on system boot
- Persistent logs via volume mount
- Health checks and resource limits
- Comprehensive deployment validation
- Easy-to-use installation scripts

Usage:
  ./scripts/deploy-production-docker.sh        # Deploy with Docker
  sudo ./scripts/install-systemd-service.sh    # Enable auto-start on boot
