feat(transfer)单击头部CheckBox时Items中IsDisabled为true的元素状态不改变

[Tony-ST0754]

refactor:OnHeaderCheck方法中过滤IsDisabled=true的子元素

Link issues

fixes #8146

问题描述 / Problem Description

使用LeftItemTemplate和RightItemTemplate时单独控制某个元素IsDisabled=true时，在单击组件头部中的CheckBox时，Items中IsDisabled=true的元素状态还是会跟着改变为：选中或未选中

根本原因 / Root Cause

当子元素IsDisabled=true时，也就是禁用了，这时单击组件头部中的CheckBox时，被禁用的子元素状态不应改变

解决方案 / Solution

修改组件中OnHeaderCheck方法，过滤掉IsDisabled=true的子元素

Reviewer's Guide

Updates the TransferPanel header checkbox handler so that bulk select/deselect only toggles items that are not disabled, leaving IsDisabled=true items’ Active state unchanged.

Hey - I've left some high level feedback:

• In OnHeaderCheck, consider filtering the result of GetShownItems() once (e.g., GetShownItems().Where(i => !i.IsDisabled)) instead of repeating the if (!i.IsDisabled) check in both branches to reduce duplication and make the intent clearer.
