Fix/补全filepath包导入 (#72)

* fix(canvas): 视频生成 - 本地素材自动迁移到 OSS 避免手动重新上传

Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>

* fix(canvas): 生成任务面板 - 默认收起避免遮挡画布空间

将任务面板默认状态从展开改为收起，减少任务生成期间对画布的视觉干扰。

Why: 面板默认展开时占用大量画布空间，影响创作体验；收起状态只显示任务数量和概要，用户可按需展开查看细节。

* fix(canvas): 素材迁移 - 补全 filepath 包导入修复编译错误

provider.go 中自动迁移逻辑使用了 filepath.Base() 但缺少 path/filepath 导入。

Why: 素材 OSS 迁移代码在第 239 行调用了 filepath.Base()，Go 编译器报 undefined: filepath。
