M3(T-M2-04/T-M3-13): LocalUploadServer 截图上传分享链路落地
补「H5 主动 POST 截图上传分享」链路，对齐原工程 OkHttpPhotoServer + savehandler：
- LocalUploadServer 从骨架实现为真实本机 HTTP server（@ohos.net.socket TCPSocketServer）：
127.0.0.1:8099 起逐端口重试 listen；手解极简 HTTP/1.1（\r\n\r\n 分隔 + Content-Length
累积读全 body）；仅 POST /testurl，body 取 base64(form name=/raw 兼容)+type → emit
PHOTO_UPLOAD → 回 200；非 /testurl 回 404；16MB 上限；异常 log 不崩溃。
baseUrl 反映实际端口。注：TCPSocketServer 无显式 close，stop 用 off('connect')+释放引用
- common ShareEvents.PHOTO_UPLOAD + PhotoUploadPayload
- ShareProvider：订阅 PHOTO_UPLOAD（仅激活槽处理，避免双实例重复分享）→ 落盘 → 微信图片
分享（type=="1"好友/其他朋友圈）→ sharesuccess；onDestroy 退订；抽 wechatImageByFriend/
wechatSceneByFriend 供面板截图与 POST 上传两条链路共用
真机验证项：H5 真实 POST body 格式、127.0.0.1 端口可达、微信开放平台注册
