fix: use applicationDisplayName instead of qAppName in DQMLGlobalObject

[18202781743]

Changed qAppName() to qApp->applicationDisplayName() when sending system
notifications to use the display name rather than the executable name.
This provides better user experience as display names are typically
more readable and user-friendly than raw executable names. The change
affects the notification sender configuration in DQMLGlobalObject's
sendSystemMessage method.

fix: 在DQMLGlobalObject中使用applicationDisplayName替代qAppName

将发送系统通知时的qAppName()改为qApp->applicationDisplayName()，以
使用显示名称而非可执行文件名。这提供了更好的用户体验，因为显示名称通
常比原始可执行文件名更易读和用户友好。此修改影响了DQMLGlobalObject的
sendSystemMessage方法中的通知发送器配置。
