Walkthrough

此次更改优化了AjaxUploader组件中onFileDropOrPaste方法的事件处理逻辑。现在，只有在检测到事件中实际包含文件时，才会调用e.preventDefault()，以避免对非文件拖拽或粘贴操作的不必要干预。

Changes

文件/路径	变更摘要
src/AjaxUploader.tsx	优化`onFileDropOrPaste`方法，增加对事件中是否包含文件的判断，仅在存在文件时调用`e.preventDefault()`，避免无意义阻止默认行为。
tests/uploader.spec.tsx	新增粘贴事件测试用例，验证带文件和不带文件的粘贴事件中`preventDefault`调用的正确性。

兔子写代码，细节不放松，
拖拽与粘贴，文件需分明。
只有真有文件，才阻止默认行，
逻辑更精准，体验更贴心。

tests/uploader.spec.tsx (2)

492-509: 测试实现正确，验证了带文件的粘贴事件处理逻辑。

这个测试用例正确地验证了当粘贴事件包含文件时，preventDefault 方法应被调用的行为。测试设置合理，使用 jest.spyOn 监视 Event.prototype.preventDefault 的调用，并在测试结束后正确恢复 spy。测试数据模拟了包含文件的 clipboardData，符合实际使用场景。

511-526: 测试实现正确，验证了不包含文件的粘贴事件处理逻辑。

这个测试用例正确地验证了当粘贴事件不包含文件时，preventDefault 方法不应被调用的行为。这是此次修复的核心部分 - 避免对非文件粘贴操作的不必要干预，从而解决了在表单中启用 pastable 设置时 FormItemInput 复制功能失效的问题。

测试设置与第一个测试保持一致，使用了正确的模拟数据（kind: 'string' 和空的 files 数组）来模拟不包含文件的粘贴事件。

这个逻辑和下面的不一样。看起来 hasFile 变量不用定义。直接在下面写 if 就行了，逻辑合并掉
