Subject: [PATCH 1/2] Update database.js

Lack of Connection Pooling and Retry Mechanism
Problem: In cloud environments, databases may experience temporary downtime. The current connection code does not handle retries or use connection pooling.
Solution: Implement a retry mechanism and enable connection pooling by configuring the MongoClient in database.js.

Subject: [PATCH 2/2] Update Todo.js

No Indexing on MongoDB Collections
Problem: MongoDB collections might become slower as data grows. Indexing can greatly improve query performance, especially in cloud environments with larger datasets.
Solution: Add indexing to the Todo and User models to ensure efficient querying.
