feat(traffic-flow): раскрытие сервисов страны на карте сети

- Контракт: countryServiceGroups (группа сервисов страны) в flowMapHopsDto, тип FlowMapCountryServiceGroup.
- Бэкенд: вложенная агрегация brand×ISO в том же проходе hops; рёбра страна→сервис, пути с реальным EN; cap 8 / min 4, доля от байтов страны.
- Хелпер mapCountryServiceNodeId: id вида cc:us|svc:google, сервисы разных стран не смешиваются.
- Карта сети: клик по стране сдвигает колонку стран и раскрывает столбец её сервисов; остальные страны приглушены; панели страны и вложенного сервиса.
- Тесты: группы US/US+NL, рёбра от страны, cap/min вложенного слоя; mock countryServiceGroups для демо-режима.
