feat: 参照dde-weather重构插件，修复显示与弹窗定位

- QML 根元素使用 AppletItem，参照 dde-weather 插件实现
- 使用 Panel.rootObject.dockItemMaxSize 适配任务栏图标尺寸
- dockOrder 设为 21，定位在系统托盘左侧
- 使用 PanelPopup + PanelToolTip + TapHandler 实现点击弹窗和悬停提示
- 弹窗打开前设置 DockPanelPositioner.bounding 修正弹窗定位
- C++ 后端新增 dbusAvailable 属性，D-Bus 不可用时优雅降级
- 使用 isServiceRegistered 正确检测 D-Bus 服务可用性
- install.sh 改用 SCRIPT_DIR 自动定位项目根目录
