fix: Fixed tab key navigation issue in notification center

[18202781743]

The changes address the tab key navigation issue in the notification
center where pressing tab couldn't close notifications. The main fix
involves converting NotifyItem from Control to FocusScope to properly
handle focus management. Additionally, all notification components
(GroupNotify, NormalNotify, OverlapNotify, NotifyItemContent) were
wrapped in Control containers with proper implicit size properties to
ensure consistent focus behavior. The close button visibility logic was
updated to use activeFocus instead of hovered state for better keyboard
navigation support.

Log: Fixed tab key navigation issue in notification center

Influence:

1. Test tab navigation through notification items
2. Verify close button appears with keyboard focus
3. Test Enter/Return key functionality on notifications
4. Verify mouse interactions still work correctly
5. Test notification dismissal with keyboard shortcuts

fix: 修复通知中心Tab键焦点问题

此次修改解决了通知中心中按Tab键无法关闭通知的问题。主要修复包括将
NotifyItem从Control转换为FocusScope以正确处理焦点管理。此外，所有通知组
件（GroupNotify、NormalNotify、OverlapNotify、NotifyItemContent）都被包
装在Control容器中，并设置了适当的隐式大小属性以确保一致的焦点行为。关闭
按钮的可见性逻辑更新为使用activeFocus而不是hovered状态，以提供更好的键盘
导航支持。

Log: 修复通知中心Tab键导航问题

Influence:

1. 测试通过通知项的Tab导航
2. 验证关闭按钮是否随键盘焦点出现
3. 测试Enter/Return键在通知上的功能
4. 验证鼠标交互是否仍然正常工作
5. 测试使用键盘快捷键关闭通知

Reviewer's Guide

This PR refactors focus and keyboard navigation in the notification center by converting NotifyItem to a FocusScope root, wrapping notification content in Control containers with implicit sizing, switching close button visibility to rely on activeFocus, adding Enter/Return key handlers for expansion, and fixing a border radius reference.
