Introduced a new `deploy` target for deploying services and a `push-images` target for building and pushing Docker images. Added a default `VERSION` and `REGISTRY` variable for streamlined image tagging and registry management. Included a `docker-compose.deploy.yml` file for deployment configuration.
Moved environment variables to .env.template for better management and updated docker-compose files to use them. Added separate docker-compose.dev.yml for development, a Makefile for streamlined commands, and split backend Dockerfile into development and production stages. Updated .gitignore to include new changes.
