fix(i18n): corrigido conflito de literais entre app e lib no PO UI

- Resolvido problema onde os literais da lib não eram carregados
  corretamente quando a lib era adicionada em um app que também
  utiliza i18n, devido ao comportamento de sobrescrição da configuração
  do app principal.
- Ajustado o comportamento do carregamento dos literais para garantir
  que cada configuração do i18n (do app e da lib) seja aplicada separadamente,
  evitando conflitos entre as configurações de ambos.

Fixes DTHFUI-10440
