fix(notification): adjust notification sound playback timing

Move the sound playback to the end of Notify function, after all
notification display logic has been processed. This ensures sound is
played at the appropriate time in the notification flow.

将音效播放移到Notify函数末尾，在所有通知显示逻辑处理完成后。
这确保音效在通知流程的适当时机播放。

Log: 调整通知音效播放时机
PMS: BUG-354203
Influence: 调整音效播放时机到通知处理流程的最后阶段，
确保音效播放的时机更加合理。
