Refactor service registry and load balancer integration

- Pass service registry to load balancer for dependency injection -
Remove dynamic imports of service registry in load balancer - Update
service registration and health check logic - Enable token-service in
docker-compose and service config - Add room names and rooms proxy
endpoints - Improve logging for proxy requests and health checks -
Update deploy script project name to sa4cps - Add test script for
coroutine fix - Minor code cleanup and formatting
