fix(admin-ui): split /dictionaries into layout + index for nested route

После regen routeTree.gen.ts /dictionaries/$name стал child route /dictionaries.
dictionaries.tsx рендерил карточки без <Outlet/> — клик по карточке менял URL,
но child компонент негде было рендерить, поэтому видна та же страница со списком.

Разнёс по конвенции:
- dictionaries.tsx — layout с <Outlet/>
- dictionaries.index.tsx — карточки списка (matches /dictionaries)
- dictionaries.$name.tsx — без изменений (matches /dictionaries/{name})
