🚚(app-desk) change next router to pages

2 routers exists in Next.js, "app" router and "page" router.
The "app" router has a bug introduced in Next.js 13.4.14, which is
not fixed yet. For the moment we cannot use dynamic routes with
"app" router with an SPA. As advised by the Next.js team, we
migrated to the "pages" router.
