Add script to build and push Docker images to registry

- Introduced `push-images.sh` script for building and pushing backend and frontend images. - Added functionality to select or input image tags. - Integrated environment variable support for registry configuration. - Implemented prompts for user confirmation before building and pushing images. - Updated `docker-compose.prod.yml` with new image tags after pushing.
