P0/P1/P2 全量自审已闭环：

• BKLOG 白名单应用固定强制当前用户业务/实例权限，阻断跨业务别名混淆；
• 详情采用字段白名单，补齐容器 configs，并递归脱敏 Kafka SSL、密码、Token、凭证与私钥；
• 列表使用 -updated_at,-collector_config_id 稳定分页；详情缺少精确检索状态时返回 unknown，不误报不可检索；
• APIGW operationId、后端路径、MCP 权限映射和路由契约均有回归测试。

分支已 rebase 到最新 upstream/master。本地验证：BKLOG 10 项、列表详情资源 16 项、MCP 契约 42 项均通过；最终复扫 no findings。
