    Add data fetching and storage script with PostgreSQL integration
    
    This commit introduces a script to fetch data from an external API, process it, and store it in a PostgreSQL database using Drizzle ORM. It sets up necessary dependencies in `package.json` and defines the database schema, connection, and logic to handle paginated API requests efficiently.
