Implement Proper Docker Support

[kjanat]

Description

We need to implement Docker support for the ChatLogger application to improve deployment consistency, portability, and scalability across different environments.

Objectives

• Create a Dockerfile for the application
• Set up docker-compose.yml for local development
• Document Docker usage in README
• Ensure all application components work properly in containers

Technical Requirements

• Create a production-ready Dockerfile optimized for JavaScript applications
• Include necessary environment configurations
• Set up proper volume mappings for persistent data
• Configure networking between containers if needed
• Implement best practices for security and performance

Acceptance Criteria

• Application can be built and run using Docker without code modifications
• Development environment can be set up with docker-compose
• All existing functionality works when running in containers
• Documentation includes clear instructions for Docker usage
• Docker images are optimized for size and security

Additional Information

• The repository is primarily JavaScript-based (98.6%)
• The application focuses on "Chatbot User Interaction and Storage"
• Docker implementation should follow best practices for Node.js applications

Implementation Notes

• Consider using multi-stage builds to minimize image size
• Evaluate if we need separate containers for different components (database, application server, etc.)
• Ensure proper logging configuration in containerized environment
