feat: 实验性连接信息导出与会话恢复，重写关于页

- SessionShare：把 userId / JSESSIONID / token 打成 Base64(JSON)，Cookie 只保留 JSESSIONID 一项，粘贴时容忍换行与空白，QR 令牌与乱码解不出来 - 主页底部新增「导出连接信息」卡片，标记实验性：内容未加密，字符串在手即可操作账号 - 登录页识别到连接信息时把登录按钮换成「恢复会话」，不必再扫 QR 令牌 - 恢复优先沿用导入的 JSESSIONID（不重发 UserLoginApi，免得顶掉机台上的登录）， Cookie 失效才退回用 token 登录；验证 Cookie 时顺手拉到的 GetUserDataApi 结果直接交给主页展示，省一次请求 - 仅凭 Cookie 恢复的会话没有 loginId / loginDateTime，_gameLogin 保持 null，票据与风险页照旧提示「尚未登录游戏服务器」，主页顶部给出说明横幅 - 关于页改用 AppCard / SectionTitle 脚手架，补基本信息与风险提示，把过时的「jsQR (web)」致谢换成原生 MethodChannel（QR 解码早已不走 web 库）
