🐛[BUG] 微软商店版的一系列BUG

🐛 描述(Description)
1.“启动时自动运行Steam”功能失效
2.“当Steam客户端启动时弹出通知”功能失效
3.”账号切换“页面内，提示没有在您的电脑上读取到任何Steam帐户数据，但在刷新后却可以直接弹出之前登录过的所有账号
4.在”账号切换“页面内，任选一个账号，并选择一键登录Steam时，无法启动Steam，且自动关闭Watt Toolkit（？），在手动启动Steam时，依旧需要手动输入账号密码及Steam令牌验证码
（PS：以上不清楚是否为我本人设置的问题，但我之前使用微软商店版时根本没有这些问题，不知道是什么时候开始问题越来越多，已经忍了好久了，实在是受不了了。另外我记得原来貌似有一个启动Steam时跳过输入密码的功能，但却找不到了？）

📷 复现步骤(Steps to Reproduce)
每次启动时都是这样，无需刻意复现

🚑 基本信息(Basic Information)

- 程序版本(Program Version):2.8.2
- 系统版本号(OS Version): Windows 11 家庭中文版 22000.856
- 是否为应用商店版本(Whether it is a Store version): 是

Start with the logged entry points WindowsPlatformServiceImpl.StartAsInvokerByExplorer, SteamServiceImpl.StartSteam, and SteamAccountPageViewModel.ReStartSteamByUser, using the Store version and the supplied Windows error as context. Trace how startup, notifications, account loading, and one-click login behave; done means the reported Store-version behaviors work without closing Watt Toolkit or requiring unexpected manual credentials.
