/**
 * 恒联数通 · 正式投入生产环境 全量测试数据一键安全清理脚本
 * 
 * 功能特点：
 * 1. 自动执行数据库全量 mysqldump 备份（带时间戳，存放在 /www/backup/database/）
 * 2. 清理所有 54 张测试数据表（账号、微信授权、订单、收益、提现、日结、任务、评价等）
 * 3. 严格保护白名单：管理员体系、系统配置、商城商品、规格价格、分类、装修页面、物流模板、素材附件等
 * 4. 重置商品真实销量为 0，保留虚拟展示销量 show_sales
 * 5. 自动清空恒联专属 Redis 数据库（DB 3），清除延迟队列与汇率缓存
 * 6. 自动清空 ThinkPHP 模板与数据缓存
 * 7. 指标自检核对（dmepa汇率回归 0.00000075，合格单 N = 0，用户数 = 0，订单数 = 0）
 * 
 * 执行方式：
 * 预览模式：php scripts/production_clean_all.php --dry-run
 * 正式执行：php scripts/production_clean_all.php --force
