fix(nodes): принимать доменное имя/FQDN в поле хоста сервера Proxmox

Поле ip_address валидировалось строго как IP, из-за чего подключение ноды по домену (node1.tzim.cloud) падало с 'Invalid IP address format'. Добавлен хелпер validate_host: принимает IP (v4/v6) или корректный hostname/FQDN. IPAM-валидаторы по-прежнему требуют строгий IP.
