🐛[BUG] 首次启动主页面时卡顿

## 请认真检查以下清单中的每一项
- [x] 已经搜索过，没有发现类似的 issue
- [x] 已经搜索过文档，没有发现相关内容
- [x] 已经尝试使用过最新版，问题依旧存在
- [x] 使用的是官方版本（未替换及修改过安装目录程序文件）

### 🐛 描述
在设置当中启用「启动时最小化到托盘」选项。
然后启动 Watt Toolkit（即启动前保证未在后台运行），然后通过托盘唤醒主页面。
此时主页面并未完整显示，此时的 UI 如下图：

需要等待几秒，让组件和布局渲染完成。时间不长，但是会造成明显的卡顿感。
后续只要不退出后台程序，再次唤醒就不会有问题。

Reproduce the first launch with “minimize to tray” enabled and wake the main window from the tray. Start by tracing the reported StartOrStopProxyService path through NetworkTestService.TestDNSOverHttpsAsync and ProxyService.GetValidDNSAsync, then inspect how the main page is rendered during startup. Done means the first tray wake shows a complete UI without the reported multi-second stall.
