feat: Завершена реализация универсальной лаборатории

- Добавлена полная поддержка Istio service mesh с Kiali
- Интегрированы Helm charts (nginx, prometheus-stack)
- Созданы Grafana дашборды для Istio мониторинга
- Добавлен HTML генератор отчетов с красивым дизайном
- Созданы скрипты для снапшотов и восстановления
- Добавлена поддержка Istio Bookinfo demo
- Обновлена документация с полным описанием возможностей

Компоненты:
- Istio с Telemetry и Traffic Policy
- Prometheus + Grafana с автопровижинингом дашбордов
- HTML отчеты с анализом статусов
- Снапшоты и восстановление состояния
- Полная интеграция с Kubernetes
