P0: - rpm_override 嵌入 Auth Cache Snapshot，消除每请求 DB 查询 (snapshot v6→v7) - 429 RPM 响应返回 Retry-After 头（当前分钟剩余秒数） P1: - ClearAll 按钮直连 DELETE API，带 loading 防重复 - 新增 GET /admin/users/:id/rpm-status 管理员 RPM 用量查询端点 优化: - checkRPM 从级联互斥改为并行取最严，user.rpm_limit 作为全局硬上限始终生效 - Override/Group 变更后自动失效 auth cache - fail-open 语义不变，Redis 故障不阻塞业务
