fix: 修复多个P0阻塞性问题

P0-01: Context值类型拷贝导致悬空指针
- GetIAMTokenClaims/getIAMTokenClaims改为使用*IAMTokenClaims指针类型
- WithIAMClaims改为存储指针而非值拷贝

P0-02: writeAuthError从未写入响应体
- 添加json.NewEncoder(w).Encode(resp)将错误响应写入HTTP响应

P0-03: 内存存储无上限导致OOM
- 添加MaxEvents常量(100000)限制内存存储容量
- 添加cleanupOldEvents方法清理旧事件

P0-04: 幂等性检查存在竞态条件
- 添加idempotencyMu互斥锁保护检查和插入之间的时间窗口

其他改进:
- 提取roleHierarchyLevels为包级变量，消除重复定义
- CheckScope空scope检查从返回true改为返回false（安全加固）
