变更摘要

本 PR 主要修复「导入意图包」弹窗取消按钮不生效、以及导入成功后弹窗不自动关闭的问题。改动集中在 import-package-modal.component.ts：将 NzModalRef 与 NZ_MODAL_DATA 的依赖注入标记为 @Optional()，并在 dismiss() 中由直接调用 modalRef.close() 改为在 modalRef 存在时调用 modalRef.destroy()，从而避免因依赖未注入导致的异常，并确保弹窗能够被正确关闭。

主要改动

• 依赖注入增加 @Optional() 标记：为构造函数中的 private modalRef: NzModalRef 和 @Inject(NZ_MODAL_DATA) public nzData: any 添加 @Optional()，使这两个依赖在未提供时不会被强制注入，避免组件因缺少依赖而创建失败。
• dismiss() 关闭方式调整：将 this.modalRef.close() 改为先判断 if (this.modalRef)，再调用 this.modalRef.destroy()，防止在 modalRef 为 null 时调用方法报错，同时改用 destroy() 销毁弹窗。
• 导入语句补充 Optional：在 @angular/core 的导入中新增 Optional，以支持上述依赖注入装饰器的使用。
