fix: corrige XPath para inline-graphic e validação de containers (#1049)

- Ajusta XPath para usar caminho relativo ao parent em vez de tag genérica
- Corrige XPath de containers para verificar ausência de graphic em qualquer nível
- Substitui list comprehension por loop explícito com getchildren() para melhor compatibilidade
