fix: Resolved issue where private update tray visibility could be controlled via the Control Center (#289)

Private update tray no longer allows users to manually set visibility
[V25 2500U1] [Update Management System] [Enterprise Update Management System] [Round 8] After the client successfully connects to a private update source, the standalone update client option in the taskbar settings should not be deselectable
[V25 2500U1] [Update Management System] [Control Center Update Client] [Round 8] [System Update] [Public Network] [Taskbar] [Update Status Plugin] For public network system updates, the "Standalone Update Client" option should not be displayed in the Control Center plugin area's update status configuration items

fix: 修复私有化托盘可见性可以通过控制中心控制的问题
稀有化更新托盘不允许用户自行设置可见性
【V25 2500U1】【更新管理系统】【企业级更新管理系统】【第八轮测试】客户端接入私有化成功后，任务栏设置中更新独立客户端应该不可取消勾选
【V25 2500U1】【更新管理系统】【控制中心更新客户端】【第八轮测试】【系统更新】【公网】【任务栏】【更新状态插件】公网系统更新，控制中心插件区域更新状态配置项不应该展示更新独立客户端
