test: 修复测试覆盖度 — 修复 LaunchOverlay 断言 + 扩展 Bridge 检测 + 补充 Phase 2 单测 

Phase 3 测试覆盖修复：
- 修复 LaunchOverlay 测试：CircularProgressIndicator + appName 替代旧 UI
- Bridge 脚本检测从 8 → 12 个 Action
- test_hooks.dart: 新增 4 个 Phase 2 测试钩子
- 新增 10 个 Phase 2 单元测试:
  · getDeviceInfo smoke test
  · getNetworkStatus (WiFi/cellular/none) 3 个
  · setStatusBar (light/dark+color/empty) 3 个
  · showToast widget test + 空消息守卫
- 全部 84 条测试通过 ✅
