test: добавить полное покрытие Molecule + HTML report генератор

Molecule тесты для всех аддонов и кластерный topology тест:

Аддоны (Helm lint + template + assertions):
- addons/technitium-dns/role/molecule/ — Primary/Secondary DNS, CronJob, kube-vip
- addons/authelia/role/molecule/ — OIDC clients, access_control, manifests
- addons/ingress-proxypass/role/molecule/ — proxies, Service/Endpoints/Ingress
- addons/ingress-add-domains/role/molecule/ — entries, Ingress per namespace
- addons/yandex-dns-controller/role/molecule/ — CronJob, ConfigMap, RBAC

Кластер:
- molecule/cluster/ — 3 master (embedded etcd HA) + 2 worker topology тест

Инфраструктура:
- scripts/molecule-report.py — генератор HTML отчётов из JUnit XML
  (читает /tmp/molecule-junit/*.xml → /tmp/molecule-report.html)
- requirements-python.txt — комментарий к отчётному блоку
- docker/entrypoint.sh — добавлены команды molecule-addon, molecule-cluster,
  molecule-report с автоматическим включением junit callback
- Makefile — targets: molecule-cluster, molecule-addon-*, molecule-addon-all,
  molecule-report; molecule-all генерирует HTML отчёт
- docs/molecule-testing.md — полная документация всех сценариев
- docs/addons.md — добавлены technitium-dns и authelia в таблицу аддонов
