feat(canvas): 画布 Memphis 化并补全编辑功能

Browse Source 
- 后端新增 POST /admin/api/my-images 上传接口:图片存入用户
  owner 目录并生成缩略图,复用 /images 服务与 my-images picker
- 本地图片三种入画布路径:上传按钮 / 拖入舞台(落点即拖放
  位置) / Ctrl+V 粘贴
- 节点选中后显示悬浮工具条(预览/复制/置顶/删除)与右下角
  缩放手柄;图片等比缩放,便签自由缩放;Ctrl+D 复制选中(含
  相互连线);双击空白建笔记;按 1 / ⤢ 按钮适应全部内容
- 整套画布 UI 换 Memphis:纸张底+墨点网格、黑边硬影节点、
  黄色贴纸便签、橙色连线/选中态、虚线框选、顶栏/生成面板/
  预览灯箱/图片选择器全部换墨边 chunky 样式,随站点明暗主题
