微信 1.8.2 兼容 iOS 17+ SDK:swizzle 弃用的 openURL: 转发到新 API

WeChat OpenSDK 1.8.2 内部仍调 -[UIApplication openURL:],本项目链接
iOS 26 SDK 时被系统强制返回 NO("BUG IN CLIENT OF UIKIT ... Force
returning false"),导致 WXApi.sendAuthReq / sendReq 一律失败、H5 拿到
authStepFailed(-3)。

WXOpenURLShim 用 method_setImplementation 把这一个 selector 的 IMP
替换为转发到 open(_:options:completionHandler:) 并同步返回 true,
作用域仅限此老 API。在 WXApi.registerApp 之前 install 一次。

daoqi/msext 用 1.8.2 没此问题,是因为它 IPA 链接的 base SDK 更低、
系统对老 app 放行 openURL:。新外壳无此豁免,需要这层兜底。
