Aligned environment variable naming across backend and infrastructure files for improved consistency (e.g., `SPRING_CLOUD_CONSUL` and `SPRING_SECURITY_OAUTH2_RESOURCESERVER`). Introduced `PING_SERVICE_URL` to support dynamic Ping-Service routing. Updated Docker Compose health checks, profiles, and memory settings for scalability and stability.
- Reorganized `docker-compose.yaml` by splitting it into modular files: `dc-infra.yaml`, `dc-backend.yaml`, `dc-gui.yaml`, and `dc-ops.yaml`.
- Simplified structure by removing redundant `docker-compose.frontend.yaml` and `docker-compose.services.yaml` files.
- Improved maintainability and modularity of service definitions across infrastructure, backend, GUI, and ops layers.
