3.7Practical Exercise

Given an API that returns paginated user lists, write functions that:

1. Collect all users across all pages into a single list
2. Verify no duplicate IDs exist across pages
3. Find users that exist in the "active users" endpoint but not in the "all users" endpoint (use sets)
4. Group users by role using a dictionary
5. Sort users by creation date and verify they are in chronological order
