-- 统一报警审核。KingbaseES（PostgreSQL 兼容模式）。
-- 部署顺序：必须先执行 migration_alarm_case_work_order_id.sql（4 表 order_id→work_order_id 改名
--   + alarm_data 删 alarm_time），再执行本脚本，日志索引使用 create_time。
--   列未先落地会因列不存在而报错。
-- 先备份，停止报警/工单写入，完整执行事务，再同时部署管理端、API 服务和前端；不要拆开执行或忽略错误。
-- audit_status 与 alarm_status 独立；确认报警创建工单，但不改变设备或报警处理状态。
-- 日志操作字典与共享 AlarmLogOperTypeEnum 对齐：0触发/1确认/2误报/3处理。
-- 仅调整结构与菜单，不迁移或补录历史数据；旧 alarm_audit 表不再由新代码读写。
