feat(ui): OpenAPIFormSection + OpenAPIQuickPicker to shadcn

- OpenAPIFormSection: antd Tooltip + @ant-design InfoCircleOutlined \u2192
  shadcn Tooltip + lucide Info. Preserves the antd Form.Item for
  spec_path since the parent form is antd-driven.
- OpenAPIQuickPicker: antd Spin + inline gray palette \u2192 lucide
  Loader2 + semantic bg-primary/10 + border-primary for selected
  cards, bg-muted/hover styling for idle. Broken logo fallback avatar
  uses bg-muted + text-foreground.

Gates: TS \u2713 | Build \u2713.
