Code Review
This pull request adds two new compound indexes to the headlines and sources collections to optimize country aggregation queries. My review focuses on the structure of these new indexes. I've identified a potential performance improvement by reordering the keys in the compound indexes to better match the query patterns used in the CountryService. This change will ensure the indexes are used as efficiently as possible by MongoDB.
… queries - Update index for headlines collection: change key order to prioritize 'status' - Update index for sources collection: change key order to prioritize 'status' - Rename indexes to better reflect their purpose and key order

Code Review
This pull request adds two new database indexes to optimize country aggregation queries on the headlines and sources collections. The changes are located in the database seeding service. My review includes a suggestion to improve the performance of the index creation process by running the operations in parallel, and to make the index names more specific for better clarity and maintainability. The code is otherwise correct and follows good practices.
