fix(P1-2): GeneratePage.tsx MOCK_MATERIALS → 真实 API

- 删除 MOCK_MATERIALS，改用 useQuery 从 /api/v1/assets 获取素材
- handleGenerate 改为 async：createEditPlan → generateEditPlan → 轮询任务状态
- 素材列表增加 loading/empty 状态展示
- materialIcon 兼容 MediaAsset.type → mime 映射
- 修复 Tag variant='danger' → 'error'（TypeScript 类型错误）
- 移除未使用的 AssetItem 导入

editPlans.ts 同步完成 P1-1：
- 全部 Mock 数据替换为真实 API 调用
- 新增 getMediaAssets/getMediaAsset/generateEditPlan/getEditPlanTask
- AssetItem → MediaAsset 映射函数

验收：npx tsc --noEmit 零错误（GeneratePage.tsx + editPlans.ts）
