P0-A: 修复鉴权体系

- check_endpoint_auth 路径归一化(无前导斜杠),v1/v2 端点级鉴权真正生效
- ADMIN_API_ENDPOINTS 重建:修复 files 单复数、补 mirrors/alerts/prewarm/api-docs/user-password
- handler check_auth 方法感知:公开端点仅 GET/HEAD,写操作默认要求认证(fail-closed)
- 补全受保护端点(monitor/activity/login-logs/mirrors/alerts/prewarm/file 元数据)
- _check_basic_auth/_check_token_auth 改用 hmac.compare_digest
- do_POST/do_HEAD 解析路径时剥离查询串;do_HEAD 增加 is_safe_path 检查
- is_safe_path 改用 realpath 防符号链接绕过
