Sdf1_login/admin_2fa_setup.php
T
ypsdf1 0b63a99719 install页去掉IP白名单门禁并修null告警, 新增0.0.0.0应急逃生通道 
- install.php: sqlMdDbConfig 全新站 java/web 槽为 null, $val 闭包加 is_array 兜底,
  消除每个输入框的 array offset on null 告警; 门禁只留令牌层(全新站无白名单可言);
  安装成功页改为回显本次写入的完整配置供截图手抄, 背景自删
- admin_2fa_setup.php: 引导页白名单框上方显示当前访问IP; 应急模式免密进 boot 模式
  并挂红徽标; secInstallPending 让位改为 !secIsEmergency(), 避免与全局应急路由
  形成 install/引导页互跳死循环
- security.php: 新增 secIsEmergency() 判定白名单含 0.0.0.0; secIpAllowed 放行该条目;
  新增 secEmergencyGate() 在限流层前把非引导页/非本机请求 302 锁回引导页(用302防浏览器缓存)
- config.php: 补 0.0.0.0 应急用法与用完必删的说明注释

*
* 访问方式（三选一）：
* A. 已登录后台，且（2FA 未启用 或 已通过 2FA 验证）→ 直接访问
* B. 被白名单挡在外面：宝塔/SSH 查 config.php 的 SEC_BOOT_TOKEN，
* 访问 admin_2fa_setup.php?boot=<令牌>（引导模式，免密码）
* C. 服务器本机 127.0.0.1 永远可访问（仍需登录，或用 boot）

* 所有配置写入 config.php 的 SEC-UPDATE 标记区（写前自动备份到 db/config_bak/）。
