feat: миграция frontend React 18 → Angular 19

Полная миграция фронтенда на Angular 19 + PrimeNG + NgRx SignalStore.

- React 18 + AntD 5 + Zustand + Vite → Angular 19 + PrimeNG 19 + NgRx SignalStore + Angular CLI
- Ноды X6: React-компоненты → чистые DOM-функции через Shape.HTML.register с effect: ['data']
- Все 5 типов нод (site, device, cross-device, splice, card) переписаны как рендереры
- Zustand store → NgRx signalStore (schema.store.ts)
- AntD компоненты → PrimeNG (p-tree, p-table, p-menu, p-toggleSwitch, p-slider, p-button)
- 13 файлов чистого TypeScript переиспользованы as-is (типы, константы, утилиты, мок, layout, ports, edges)
- Структура файлов переименована в kebab-case
