fix: 修复模型默认值不加载 + DependentFormItem prop 透传断裂

- DependentFormItem 透传 Form.Item 注入的 value/onChange/disabled prop
- 稳定化 constraintsConfig 空对象引用(EMPTY_OBJ)，避免 useMemo 失效导致无限重渲染
- useLayoutEffect 手动 setFieldsValue(initialValues)替代 antd 被忽略的 initialValues prop
- handleReset 使用 resetFields + setFieldsValue 组合确保默认值归位
