feat: adiciona validações e testes para métodos do data-consult service

- Adiciona validações para stores(), sellers(), billings(), customers(), getAllProducts(), getAllCarriers() e getRegions()
- Valida se dados retornados têm propriedades necessárias
- Valida se resultado do repository é array válido
- Filtra dados incompletos ou com propriedades inválidas
- Refatora testes criando helper para reduzir duplicação
- Adiciona testes que expõem problemas e validam correções
- Melhora tratamento de erros com logging adequado
