fix(stats): show network-only loss in performance overlay

[qiin2333]

改了啥呀

• 性能覆盖层的丢包率改为展示 common-c 网络重组层确认的帧丢失率
• 从 native bridge 到 ArkTS 统计快照贯通 networkFrameLossPercent
• 保留原有 packetLoss 给 ABR 和串流战报使用，才不会把杂鱼指标偷偷换口径啦
• common-c 依赖：feat(stats): expose network frame loss rate qiin2333/moonlight-common-c#24（目标分支 mic，提交 b546795）

为啥要改

原覆盖层使用客户端滑动窗口统计，可能包含解码器或渲染路径的主动丢帧，无法只代表网络质量。新指标复用 common-c 的 3 秒连接状态采样，表示 FEC 后仍不可恢复的网络视频帧丢失。

验证

• npm run check:scripts 通过
• common-c 协议测试 3/3 通过
• 最新 mic 基线下完整 HarmonyOS Release HAP 构建成功
• git diff --check 通过

Summary by CodeRabbit

• 新功能

  • 新增更准确的视频网络丢帧率统计，性能监控中的丢包数据更加可靠。
  • “相位调谐”设置现已对所有用户开放，可直接启用或关闭。
  • 有界低延迟 PTS 呈现默认开启，带来更流畅、低延迟的画面呈现体验。

• 问题修复

  • 修正性能叠加层读取丢帧率数据不准确的问题。
  • 优化相关设置的默认值及持久化读取行为，确保配置状态一致。

Layer / File(s)	Summary
网络帧丢失率统计链路 nativelib/src/main/cpp/moonlight-common-c, nativelib/src/main/cpp/moonlight_bridge.cpp, entry/src/main/ets/service/streaming/StreamingSession.ets, entry/src/main/ets/components/PerformanceOverlay.ets	native 层新增 networkFrameLossPercent 输出。StreamingSession 保存并返回该字段。PerformanceOverlay 改用该字段显示网络帧丢失率。
主机节奏呈现默认值与设置入口 entry/src/main/ets/model/StreamConfig.ets, entry/src/main/ets/service/SettingsService.ets, entry/src/main/ets/service/streaming/StreamingSession.ets, entry/src/main/ets/pages/SettingsPageV2.ets	enableHostPacedPresentation 的默认值改为 true。设置页移除开发者模式限制，所有用户均可切换并保存该设置。

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 4eff4

The PR changes the performance overlay to show network-only frame loss while also broadening host-paced presentation defaults. It is mergeable with explicit owner awareness that the pinned common-c revision must be confirmed compatible with the new estimator API; no higher-severity merge-blocking issue is identified.
