Subject: [PATCH] fix: stabilize AlertToolTip overlay parenting
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. Add shown property and derive visible state from it
2. Resolve the overlay through target.Overlay.overlay to avoid
 parent-dependent lookup
3. Bind parent to the overlay while shown and restore target
 when hidden
4. Update EditPanel to control shown instead of visible

Influence:
1. Verify alert tooltip appears above edit controls
2. Confirm show/hide cycles emit no binding loop warnings
3. Verify timeout expiration hides the tooltip correctly
4. Confirm tooltip returns to target when hidden

fix: 稳定 AlertToolTip 的 Overlay 父级切换

1. 新增 shown 属性，并由其派生 visible 状态
2. 通过 target.Overlay.overlay 获取 Overlay，避免依赖当前父级查询
3. 显示时将父级绑定到 Overlay，隐藏时恢复为 target
4. 更新 EditPanel，使用 shown 代替 visible 控制提示框

Influence:
1. 验证告警提示框在编辑控件上方正确显示
2. 确认显示/隐藏循环不再产生 binding loop 警告
3. 验证超时后提示框能够正确隐藏
4. 确认隐藏时 tooltip 父级正确回到 target
