[#385] Centralize Docker Compose configurations using a dynamic template

This commit streamlines the deployment process by consolidating the Docker Compose configurations into a single template file, which is then dynamically adjusted by the Makefile based on specific deployment environments. This enhancement reduces redundancy and facilitates easier management of environment-specific settings. The transition involves updating the `Makefile` and `config.mk` to support the generation of Docker Compose files from the template, as well as modifying the `README.md` to align with the new configuration approach. This change marks a significant improvement in the deployment workflow, making it more efficient and maintainable.
