Podemos declarar um modelo `UserBase` que serve como base para nossos outros modelos. E então podemos fazer subclasses desse modelo que herdam seus atributos (declarações de tipo, validação, etc.).

Toda conversão de dados, validação, documentação, etc. ainda funcionará normalmente.

Dessa forma, podemos declarar apenas as diferenças entre os modelos (com `password` em texto claro, com `hashed_password` e sem senha):
