feat: GPU切换回退保护逻辑

- switchGpu切换前写入备份文件(.gpu-switch-backup)记录之前模式 - init()检测未确认的切换，启动30秒自动回退计时器 - QML弹出'显示是否正常'确认覆盖层，支持手动确认/回退/超时自动回退 - confirmSwitchSuccess()用户确认正常后删除备份 - restoreFromBackup()自动恢复之前模式并发送通知 - primeOffloadEnabled属性检测当前PRIME offload状态 - switchGpu改用environment.d方式，不需要root/pkexec - 翻译更新：回退确认相关8条新增
feat: GPU切换确认弹窗、按钮选中状态、文字对比度优化
