修复: 版本更新与设置面板走查问题

- 更新链路: 检查记录远端SHA256,下载完成事件回传,安装时带哈希校验
- 续传: 服务器忽略Range返回200时截断重下防追加损坏,文件名去query
- 定时器: 自动检查可重入,配置变更免重启生效,关闭即停,下载加互斥
- 前端: 支持跳过此版本并按版本去重,手动检查不受门禁限制,启动未就绪延时重试
- 更新面板: 新增自动检查开关/间隔/地址配置与进度条状态映射
- 版本历史: cache参数强制刷新与加载超时重试兜底
- 配置: 侧边栏分区全链路持久化,保存请求复用api类型防字段丢失
- 侧边栏: 区块定位改显式类名,不再依赖排序位置
- 绑定: 重新生成并与镜像目录同步
