feat(asset): 素材库补齐拖拽上传与任务模板封面入库

- AssetPicker: 「上传到素材库」区支持拖拽上传（dragover/dragleave/drop），
  抽出 uploadAndSelect 统一点击与拖拽两条路径的上传入库+自动选中逻辑，
  增加拖拽态高亮与「点击或拖拽文件到此处」提示
- GuidePackages: 封面图上传端点由失效的 /api/upload（无鉴权、后端无此路由）
  改为 /api/admin/file-record/upload（Bearer + category=guide-packages），
  修正 handleUploadSuccess 取 res.data.url，并接入「从素材库选择」AssetPicker
- 回填脚本: file_type 回填的 WHERE 条件与注释声明的意图对齐
  （排除与目标值相同的行，避免无意义行更新）
