`BaseUser` содержит базовые поля. Затем `UserIn` наследуется от `BaseUser` и добавляет поле `password`, то есть он будет включать все поля обеих моделей.

Мы аннотируем возвращаемый тип функции как `BaseUser`, но фактически возвращаем экземпляр `UserIn`.

## Log Message Guidelines

- Logger: `LogManager.getLogger(ClassName.class)`
- Format: `key=value` (e.g., `userId={}`, `url={}`)
- Prefix with `[name]` when context identification is needed
- Mask sensitive values (passwords, tokens)

## i18n / Localization

`BaseUser` has the base fields. Then `UserIn` inherits from `BaseUser` and adds the `password` field, so, it will include all the fields from both models.

We annotate the function return type as `BaseUser`, but we are actually returning a `UserIn` instance.

`BaseUser` tem os campos base. Então `UserIn` herda de `BaseUser` e adiciona o campo `password`, então, ele incluirá todos os campos de ambos os modelos.

Anotamos o tipo de retorno da função como `BaseUser`, mas na verdade estamos retornando uma instância `UserIn`.

`BaseUser` a les champs de base. Puis `UserIn` hérite de `BaseUser` et ajoute le champ `password`, il inclura donc tous les champs des deux modèles.

Nous annotons le type de retour de la fonction en `BaseUser`, mais nous renvoyons en réalité une instance de `UserIn`.
