feat(admin-ui): scope accent on dictionary detail page

Перенесли scope-визуальные константы (SCOPE_ORDER, SCOPE_DOT,
SCOPE_ACCENT) в `lib/scope-style.ts` для переиспользования. На detail
странице (`dictionaries/$name`) добавили top accent strip 4px цветом
scope + цветной чип в breadcrumb рядом с back-link. Теперь при переходе
из списка в карточку scope сразу виден без чтения badge в таблице.
