fix(web): 首页只留下载、去登录/在线体验入口; 下载区改二维码; 修复网络版一直提示新版本

- Landing: 移除 header 登录/进入应用按钮、hero 在线体验入口
- 下载区: 复制链接行改为 qrcode.react 二维码 (扫码下载 APK)
- 修复 '持续提示新版本可用' bug: vite 构建时把 BUILD_ID 写入 dist/.build-id,
  manifest-web 返回当前部署 dist 的 build_id, 与浏览器内置值同源比对;
  此前返回 OTA 包 build_id (seq-<ts>) 与页面 BUILD_ID 永不一致 → 横幅常驻
