M3(批3): 微信分享 + 登录（@tencent/wechat_open_sdk）

依赖：ohpm i @tencent/wechat_open_sdk@1.0.19（feature_capabilities）

T-M3-13 ShareProvider：friendsSharetypeUrlToptitleDescript → SendMessageToWXReq(scene 会话/朋友圈)
        + WXWebpageObject → 回传 sharesuccess{success(2成功/3取消),type(1好友/2朋友圈)}。
        type 2截图/3图片/4视频暂回退网页分享（TODO）；微信未安装回 cancel 不卡死
T-M3-14 LoginProvider：accreditlogin("1"=QQ空实现/其他=微信) → SendAuthReq(scope snsapi_userinfo) → 取 code。
        🔴 AppSecret 不入端：code 换 profile 必须服务端，无端点时记录 code+TODO，不推不完整 sharelogin（红线）
WeChatApi 单例：createWXAPI(AppID wxd2bd650e06bdfe58 公开标识) + sendReq + handleWant 路由 onResp
EntryAbility.onCreate/onNewWant → WeChatApi.handleWant（接收微信回调）
module.json5：querySchemes ["weixin"]（isWXAppInstalled）

运行期成功前提（已注释说明）：微信开放平台注册本 HarmonyOS 应用(bundleName+指纹绑 AppID)、登录 profile 需服务端 code 换取端点。
devecocli build 通过（CompileArkTS 编译微信代码无误）。
