Pull request overview

This PR optimizes Docker configuration for production deployment by reducing image size and memory footprint. The changes switch from development mode to production mode execution and leverage multi-stage builds with Alpine images.

Key changes:

• Implemented multi-stage Docker build using node:20-alpine base images to reduce image size from ~2GB to ~1GB
• Updated production startup command to use compiled output path (dist/src/main.js)
• Removed MySQL service from docker-compose.yml as the application uses RDS in production
