feat(skd): multi-series и multi-point в StructureItemChart

Диаграмма может содержать несколько <dcsset:series> (и аналогично
<dcsset:point>) — каждая со своим groupItems, filter, order, selection,
viewMode, userSettingID и userSettingPresentation. Используется для
multi-series графиков с группировкой по фильтру (например,
АнализЛояльностиКлиентовXYZ — series по СтадияОтношений: Постоянный,
Разовый, Потенциальный, Потерянный клиент).

Раньше декомпилировали только первый блок (SelectSingleNode), теряя
остальные → −113 строк diff на одном этом отчёте (134 → 21).

decompile: SelectNodes → если >1, сохраняем как массив; single → object
(backward-compat).
compile: проверяем тип points/series — array → цикл, иначе single
блок (backward-compat для существующего DSL).

PS и Py compile синхронизированы.
