Two access to the database in the login method

[gussttaav]

The following section of code accesses the database twice: once to retrieve the UserDetails required by Spring Security, and again to obtain all user data to return in the request. Also, the ResourceNotFoundException is never thrown if the user's email does not exist; the UsernameNotFoundException exception is thrown first when usuarioDetallesService.loadUserByUsername is called.

UserDetails userDetails = usuarioDetallesService.loadUserByUsername(loginDTO.email());

Usuario usuario = usuarioRepository.findByEmail(loginDTO.email())
    .orElseThrow(() -> new ResourceNotFoundException(
        "No existe ningún usuario con el email proporcionado"
    ));
