M3(T-M3-13): 分享面板对齐原工程——微信SDK + QQ/抖音系统分享

对齐 Android SharePanelHelper 流程:H5 friendsSharetypeUrlToptitleDescript →
原生弹自定义面板(微信/QQ/抖音) → 按所选平台分享。

- common ShareEvents:SHOW_PANEL + SharePanelRequest/Result;ShareProvider 经一次性
  resultEvent 与 entry 容器一对一解耦(双槽实例隔离,避免广播串扰)
- ShareProvider 重构:微信走 SDK(type2 Canvas截图→WXImageObject / 其他→WXWebpageObject;
  scene 好友/朋友圈;回传 sharesuccess);QQ/抖音走 @kit.ShareKit 系统分享(文本/图片/链接/视频,
  不集成对应 SDK、不回传);截图失败统一降级
- 截图:CapabilityContext.captureCanvas(WebSlot 用 controller.runJavaScript 取 canvas
  toDataURL,非激活/出错返回空);FileSystem.writeBytes 落盘;fileUri 给 WXImageObject/系统分享
- entry SharePanel 组件 + BridgeGameContainer 顶层叠加;重复面板/销毁均取消回投防 once 悬挂

真机验证项:微信开放平台注册后的真分享、系统分享面板拉起、canvas 截图
