feat(tgu-ops-ui): display request polygons on 2D map

Добавлен слой заявок (КНС) на 2D карту ТГУ:
- requestApi.ts — загрузка заявок постранично через GET /v1/requests/map
  с прогресс-коллбэком; автоматически собирает все страницы
- wktParser.ts — парсинг WKT POLYGON/MULTIPOLYGON в массив координат
- drawRequests.ts — Canvas-рендеринг полигонов заявок
- Tgu2DMapLayers.ts — buildTgu2DMapScene строит MapPolygon[] из RequestMapItem[]
- Tgu2DMapTab.tsx — состояние requestsState, кнопка «Загрузить», фильтры по дате
- Tgu2DMapSidebar.tsx — панель слоя заявок: счётчик, ошибки, truncated-предупреждение
- requestTypes.ts — RequestMapItem, RequestMapPage модели
- Поддержка выбора заявки на карте (mapSelectionTypes, mapTypes)
- nginx.conf, vite.config.ts — проксирование /v1 на pcp-request-service в dev
