fix: fix notification bubble animation glitch

1. Replaced the previous complex ScriptAction with a simpler
PropertyAnimation for the add transition
2. Added a new addDisplaced transition to handle displaced items when
new notifications are added
3. Removed the manual script that forced previous bubble animations to
complete, which was causing visual glitches
4. Now uses standard Qt Quick transitions for smoother and more reliable
animation behavior

fix: 修复通知气泡动画显示问题

1. 将之前复杂的 ScriptAction 替换为更简单的 PropertyAnimation 来处理添加
动画
2. 新增 addDisplaced 过渡动画来处理新通知添加时其他气泡的位移
3. 移除了强制完成前一个气泡动画的手动脚本，该脚本会导致视觉故障
4. 现在使用标准的 Qt Quick 过渡动画来实现更平滑可靠的动画效果
