Remove cpu from resource limits while keeping memory limits and all
requests intact. CPU limits cause unnecessary throttling and
overcommit alerts when actual usage is far below limits.
Refactor Kubernetes resource definitions to replace the label
"app" with "app.kubernetes.io/name" for the dancefinder-app.
This change enhances consistency with Kubernetes best practices
and improves clarity in resource labeling across deployments,
services, and autoscalers.
