WM_AsyncServerCandidateKey 对所有候选键都用 300 ms 提交预算，回复缺失即按 「可能已上屏」处理：丢键并完整重置传输。可对 PageUp/PageDown/Up/Down/Tab（含 Shift+Tab）来说，Server 只翻页或移动高亮，回复本来就只是确认（处理函数原先的 注释也这么写），永远不会上屏。把一次慢确认升级成拆管道、清组合，代价完全不对等。 现在这几颗键走普通的 50 ms 软读取：超时只是软错过，不拆管道、不清队列，迟到 的回复按 request id 缓存；只有真正的读失败/坏帧（TransportUnavailable）才按传输 失败处理。回复内容一律不应用，因为 Server 对这些键从不提交文本。 逗号、句号、括号、减号/等号（可配置翻页，也可能以词定字或随标点上屏）、 Ctrl+Enter 译文上屏和选词键仍保留 300 ms 提交预算与「歧义即丢键 + 传输重置」。 判定放在 IsCandidateNavigationOnlyKey 里并补了单元测试。
