Problem
Our data pipeline fetches paginated API responses. Write a function called aggregate_pages that takes a list of page results, where each page is a list of dictionaries with 'category' and 'amount' keys. Combine all pages and return a dictionary mapping each category to its total amount, sorted by total descending.
