refactor: standardize environment variable naming and add PING_SERVICE_URL configuration

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.
