🐛[BUG] ProFormField 如有initialValue，会导致ArrowLeft和ArrowRight不能用

### 🐛 bug 描述

在edit form里，没办法用左右方向键去调整当前输入的位置。
经过debug发现当前event有`defaultPrevented : true`

### 📷 复现步骤

加个listener
```
useEffect(() => {
const handler = (e: KeyboardEvent) => {
if (e.key.startsWith('Arrow') && e.defaultPrevented) {
console.log('Arrow key prevented')
console.log(e);
}
};

document.addEventListener('keydown', handler);
return () => document.removeEventListener('keydown', handler);
}, []);
```

> Add New Record ( 没初始value）

> Edit Existing Record ( 有初始value )

### 🏞 期望结果
左右键应该要正常运作，可以调整输入位子

### 💻 复现代码
> Add New Record
```

title='Add New Material'
trigger={
}>
Add Material

}
formRef={formRef}
autoFocusFirstInput
modalProps={{
destroyOnHidden: true,
maskClosable: false,
keyboard: false,
}}
width={850}
>




```

> Edit Existing Record
```

title='Edit Material'
trigger={trigger}
formRef={formRef}
autoFocusFirstInput
modalProps={{
destroyOnHidden: true,
maskClosable: false,
keyboard: false,
}}
width={850}
initialValues={materialService.transformToUpdateMaterialDto(material)}
>




```
>transformToUpdateMaterialDto 没什么特别，也就map dto而已
```
function transformToUpdateMaterialDto(material: MaterialDto): UpdateMaterialDto {
return {
....,
material_apn_desc: material.apnDesc
}
}
```

### 🚑 其他信息

Start by reproducing the edit-form case using ModalForm with initialValues and ProFormText, then compare it with the add-new-record case. Trace where keyboard handling affects ArrowLeft and ArrowRight when the field has an initial value; done means both keys move the input caret normally without preventing the event.
