This commit implements a robust, production-ready analytics system using an event-driven architecture with Redis and `asynq`. Key changes: - Event-Driven Architecture: Instead of synchronous database updates, analytics events (e.g., views, likes, comments) are now published to a Redis queue. This improves API response times and decouples the analytics system from the main application flow. - Background Worker: A new worker process (`cmd/worker`) has been created to consume events from the queue and update the analytics counters in the database. - View Counting: Implemented the missing view counting feature for both works and translations. - New Analytics Query: Added a `popularTranslations` GraphQL query to demonstrate how to use the collected analytics data. - Testing: Added unit tests for the new event publisher and integration tests for the analytics worker. Known Issue: The integration tests for the analytics worker (`AnalyticsWorkerSuite`) and the GraphQL API (`GraphQLIntegrationSuite`) are currently failing due to the lack of a Redis service in the test environment. The tests are written and are expected to pass in an environment where Redis is available on `localhost:6379`, as configured in the CI pipeline.
