This pull request introduces improvements to the application's Docker setup, dependency management, and database configuration. The most important changes include creating a multi-stage Dockerfile for optimized builds, adding the morgan logging library as a dependency, and updating the database file path for better organization.

Docker setup improvements:

• Dockerfile: Created a multi-stage build process to optimize the Docker image. The first stage installs production dependencies and removes unnecessary files, while the second stage creates a lightweight image with the built application.

Dependency management:

• package.json: Added morgan (a logging middleware) as a dependency to enhance request logging capabilities.

Database configuration:

• server.js: Updated the database file path from ./users.db to data/users.db to improve file organization within the project.
