fix(chanmama): 导出确认弹窗被浮层清理误删与代理出口拉黑修复

浮层清理只删可见浮层——页面常驻 90+ 个 display:none 弹窗模板(含导出确认框
模板)，误删后 Vue 只在游离节点上"打开"弹窗，页面上仅剩灰色遮罩与滚动锁，
导出等待 1320s 必超时；导出等待改为逐秒弹窗状态机(可点即点/点不到先关/卡死
强删并补点导出)，导出失败落截图与 HTML 诊断；浏览器强制直连并切换真 Chrome
非 stealthy 模式(StealthySession 下蝉妈妈前端会静默压制弹窗渲染)；导出按钮
原生可信点击优先，防 @click 绑定在内层元素时 JS 合成点击无效。
