feat: constraints_config.requires 联动控制 — enable_switch 开关同步启用/禁用依赖字段
- DependentFormItem: 透传 disabled 为顶层 prop(之前藏在 config.disabled 中,widget 组件读取不到)
- ImageInput: 值语义分层 — undefined(开关关) / [](开关开但空) / [{...}](已上传)
- isValueEmpty: 空数组[] 不再视为空,配合 enable_switch 语义
- handleFileWidgetValue: 兼容 Upload DOM事件 和 enable_switch 裸值两种 onChange 形态
