Merge branch 'develop' into refactor/template-editor-api

将 template-editor.ts 单文件拆分为目录结构，按业务模块组织：

- types.ts — 所有类型定义（EditPlan/Clip/MediaAsset 等）
- constants.ts — 常量（TRANSITION_OPTIONS/QUALITY_OPTIONS 等）
- editPlans.ts — 模板草稿 CRUD + 生成 + 复制 + 取消
- clips.ts — 片段 CRUD + 批量操作（重排序/批量删除/从素材创建）
- aiFeatures.ts — AI 推荐 + AI 封面生成
- mediaAssets.ts — 素材库 API + AssetItem→MediaAsset 映射
- index.ts — 统一入口，re-export 所有类型/常量/函数

入口文件从 744 行精简到 88 行（仅 re-export），
各模块职责单一，便于维护和 tree-shaking。
导入路径 @/api/template-editor 保持向后兼容。
