P1: subscription 续期包裹 Ent 事务确保原子性
P1: CSP nonce 生成处理 crypto/rand 错误,失败降级为 unsafe-inline
P1: singleflight 透传数据库真实错误,不再吞没为 not found
P1: GetUserSubscriptionsWithProgress 提取 calculateProgress 消除 N+1
P2: billing_cache/gateway_helper 迁移到 math/rand/v2 消除全局锁争用
P2: generateRandomID 降级分支增加原子计数器防碰撞
P2: CORS 非白名单 origin 不再设置 Allow-Headers/Methods/Max-Age
