feat(admin-web): preserve template wizard entry source and refresh AI banner

- Carry `from=workspace` query from the workbench into the wizard so cancel
  and post-generate redirects return to the workbench instead of always
  landing on /articles/templates.
- AppShell now resolves an effective navKey from `route.query.from`, so the
  sidebar highlight and breadcrumb track the entry source while inside the
  wizard.
- Redesign the brand-info AI analyze CTA into a standalone banner with
  template-aware copy (default / product_review / research_report) and add
  the matching i18n keys.
- Drop the unused 批量生成文章 button and its styling from the templates
  page.
