Add 'IsPultosch' field to User struct and related functions

The User struct has been expanded to include a new field 'IsPultosch', to provide additional user behavioural options. The default value for 'IsPultosch' is 'false'. Adjusted related functions to accommodate this change. This field enhances the user information for the later implementation of personalized features.
