feat(套餐真流量预警): AUG26-004 真流量预警规则、达量扫描通知与导出
新增 000228 迁移：规则表 tb_package_traffic_alert_rule（每套餐商品至多一条，无软删除，package_id 非部分唯一约束）、达量预警快照表 tb_package_traffic_alert（以主套餐使用记录 + 阈值快照为唯一键， 触发时冻结用量、额度、比例、阈值、到期时间、归属与资产快照），并为 tb_package_usage 新增扫描 范围部分索引 idx_package_usage_alert_scope；down 在预警表存在数据时阻断回滚。 新增规则维护接口 GET/POST/PUT /api/admin/package-traffic-alert-rules（仅超级管理员与平台账号）： 创建校验套餐存在且真流量额度大于零，阈值为 1%～100% 的两位小数；修改只影响后续扫描，不回填也 不改写既有预警快照；全部写操作记录操作者、前后值与时间。 新增每日 06:00（Asia/Shanghai）扫描任务 package:traffic:alert:scan，与套餐临期扫描共用 data_cleanup 队列：按资产汇总当前有效套餐的真流量，分子取使用记录真已用量、分母取使用记录真总量快照，命中 主套餐规则阈值时在同一事务创建预警与可靠通知事件；重复执行以唯一冲突视为已处理，不重复投递， 不建停机锁、不调用运营商。 新增预警列表、详情与异步导出 GET /api/admin/package-traffic-alerts、GET /api/admin/package-traffic-alerts/:id、 POST /api/admin/package-traffic-alerts/export，列表与详情一律读冻结快照；新增通知类型 package.traffic.alert 与受控目标 package_traffic_alert_detail，目标解析仅对超级管理员与平台账号 返回可跳转，越权与不存在统一按资源不可见处理。 同步 OpenAPI（cmd/gendocs、cmd/api/docs.go、pkg/openapi/handlers.go）、审计动作与资源注册、上下文 健康检查证据；归档变更并同步 package-traffic-alert 主 Spec。
