Add 9 management scripts to simplify CodiMD operations:
- start.sh: Start services with automatic .env setup
- stop.sh: Stop all services gracefully
- restart.sh: Restart all services
- logs.sh: View real-time logs for any service
- status.sh: Check service status and resource usage
- backup.sh: Backup database, uploads, and environment
- restore.sh: Restore from backups with interactive selection
- update.sh: Update Docker images with automatic backup
- cleanup.sh: Clean unused Docker resources

Add SCRIPTS.md with comprehensive usage documentation and examples.
