feat: Service Registry + Bridge 解耦架构 + 全工程代码清理

## 架构升级：Service Registry + Bridge 模式

- 新增 PluginSDK/IPluginServices.h：10 个纯虚服务接口(IDataProvider/ILinkProvider/...)
- 新增 MavLinkServiceBridge：单 QObject 实现全部服务，隔离 MavLinkNode 依赖
- 升级 PluginManifest：支持 plugin.json 的 provides/consumes 声明式依赖
- 实现 ExtensionHost::autoWire()：元对象自省自动连接信号槽
- 集成到 AppController：initModules() 中创建桥接器并注册到 ServiceRegistry
- CockpitPlugin 演示服务发现：initialize() 中通过 PluginContext 查找服务

## 代码清理

- Plugins/opmap：~280 行死代码(waypointsetting 100行注释块/tilematrix 54行/等27个文件)
- Plugins/MavLinkNode：~200 行 GBK 乱码注释翻译为 UTF-8 + 12 行注释死代码
- Plugins/ToolsUI：~222 行死代码(ECU.cpp 82行/INS.cpp 113行/Parse/ToolsUI 等)
- StatusUI/Setting/MissionUI：~65 行注释死代码
- Cockpit/leftladder.cpp：10 处 GBK 乱码翻译为中文
- 清理头文件注释掉的 #include(19 处)、空 if-else 分支、注释变量声明

## 编译验证

- [100%] Built target GCS 零错误
- 运行时 timeout 3s 正常退出，无崩溃
