feat: 新增 frpc 状态与日志管理的 Pinia store

实现 frpc 状态、运行版本和实时日志的全局管理，日志在组件切换后仍保留，订阅事件在应用根组件初始化一次。同时调整仪表盘页面使用 store 中的状态，启动后禁用版本选择下拉框，解决切换页面后日志清空的问题。

 - 将frpc的运行日志实时显示在仪表盘页面的日志区域内，并且可以清楚等

+##### 3.5.1 仪表盘功能优化调整
+
+- frpc服务启动后，还可以在下拉列表修改frpc版本，启动后就不能再修改版本，而且下拉列表里面要显示正在使用的frpc版本
+- 切换菜单之后再切回仪表盘页面，实时日志内容没了，需要保持实时日志内容不会随页面切换而清空
