Release 2024.12.1

This hotfix release addresses the following issues:

• #850 - the /data_objects/study/{study_id} endpoint was still looking for class hierarchy information in the type field, whereas the code that generates the alldocs collection had been modified to store that information in a different field
• #725 - core functionality of that endpoint was not being tested
