PR Summary

• Enhancements to Testing Procedure
  In members/tests/test_admin_admin_actions.py, there have been some important changes. A new case was added, represented by a person_without_age, who doesn't have a specified birthday. This helps to test the system's functionality when incomplete data is present. Additionally, the method create_person_and_waiting_list_entry() has been updated to efficiently handle scenarios where age or birthday remains unspecified.

• Improvements to Age Verification Utility
  The age verification utility, located in members/utils/age_check.py, has received some crucial updates. If the person.birthday is missing, the methods check_is_person_too_young() and check_is_person_too_old() will now appropriately handle this by assuming that the person is excessively young or old. This change ensures the smooth functioning of age verification, even when the birthday data is incomplete.
