fix(workshop): AI创作弹窗v5输入框布局对齐WorkBuddy参考(输入区在上/工具栏在下/外框圆角)

* data-pages.js confirmAiScript HTML 重排:paperclip/textarea/send 横向→textarea 上+toolbar 下
  (toolbar 内 paperclip + spacer + send)
* style.css:
  - .req-input-box flex row→column;border-radius 12→14;padding 0(让内部块各自控)
  - .req-input width:100%+box-sizing:border-box;padding 10/14/6
  - 新增 .req-input-toolbar(.req-spacer flex:1 推开两钮)
  - .req-send 34×34→32×32 圆角50%(贴合 WorkBuddy 圆形发送)
  - .req-paper 28×32→32×32(与 send 视觉对齐)
* CDP 9224 验证:结构(列向/圆角/toolbar 位置/按钮分布)全绿+autoGrow 多行自然下移
* 设计:req-create 仍保留在 .req-bar 左侧独立(对应弹窗外功能,不入输入框)
