Condition builder disabled 后还能拖动和删除

#### 描述问题：

设置 Condition builder 的 disabled = true 后还能操作拖动和删除，如图所示。预期是在设置 disabled 后不能对条件进行任何操作，或者提供一种【展示模式】，给用户展示已经设定好的条件，但不显示任何操作按钮。

"type": "form",
"debug": true,
"body": [
{
"type": "condition-builder",
"label": "条件组件",
"name": "conditions",
"disabled": true,
"description": "适合让用户自己拼查询条件，然后后端根据数据生成 query where",
"fields": [
{
"label": "自定义",
"type": "custom",
"name": "a",
"value": {
"type": "input-color"
},
"operators": [
{
"label": "等于（自定义）",
"value": "custom_equal"
},
{
"label": "属于",
"value": "belong",
"values": [
{
"type": "input-text",
"name": "color1"
},
{
"type": "tpl",
"tpl": "~"
},
{
"type": "input-text",
"name": "color2"
}
]
}
]
}
]
}
]
}
}
```

5. 操作步骤
官网文档中粘贴 schema 即可复现。

Reproduce the issue by pasting the provided schema into the AMIS documentation site and interacting with the disabled condition-builder. Then inspect the condition-builder entry point and its disabled-state handling. Done means disabled conditions cannot be dragged, deleted, or otherwise modified, with any display-mode behavior matching the agreed requirement.
