fix(beautify): E 批收尾 补齐 11 处 image 缺失 mode

- 头像类统一 mode=aspectFill（assessment/apply、assessment/purchase、
  guide/hierarchy x3、invite/join-form、user-edit、guide/register 规划师照片）
- 证书照片 mode=aspectFit（保留完整证件比例）
- 空状态图/加载箭头 mode=aspectFit（team-customers）
- 全站 image 共 125 处，缺 mode 从 12 降到 1（仅剩 components/mp-html 内部
  渲染器，属既有第三方代码，保持原样）
- 静态图片盘点：33 张合计 0.10MB（最大 logo.png 23KB），无需压缩
- 7 文件 node --check 通过
