Replace DAbstractDialog with DBlurEffectWidget to implement window blur
effect. Add dynamic theme adaptation for button styling. Optimize window
size and layout for better visual consistency.

使用DBlurEffectWidget替代DAbstractDialog实现窗口模糊效果。添加按钮
样式的动态主题适配功能。优化窗口尺寸和布局以提升视觉一致性。

Log: 优化许可协议对话框的模糊效果和主题适配
PMS: BUG-349395
Influence: 许可协议对话框现在支持模糊背景效果，按钮样式会根据主题
自动调整，提供更好的视觉体验和主题一致性。
