feat(admin-ui): minimal React+Vite+TanStack scaffolding

- Vite 7 + React 19 + TanStack Router (file-based) + TanStack Query
- Tailwind v4 (CSS-first config, OKLCH brand colors)
- i18next + react-i18next с RU/EN switcher в header
- Axios client с Accept-Language interceptor + JWT placeholder
- 2 pages: /dictionaries (list cards) + /dictionaries/$name (records table)
- Dockerfile (node build + nginx serving + API proxy)
- README + .gitignore

Backend:
- Новый GET /api/v1/dictionaries в read-api (DictionaryListController),
  фильтрует по доступному scope через ScopeContext
- DictionaryListItem DTO без heavy schema_json

routeTree.gen.ts — stub; реальное содержимое генерится Vite plugin'ом при
первом 'pnpm dev'.
