fix: use public ingress URL for frontend API requests (fixes #3)

The PUBLIC_API_URL was hardcoded to use internal k8s service DNS
(http://logtide-backend:8080) which cannot be resolved by browsers
outside the cluster.

Now the chart automatically derives the API URL from the ingress
configuration when enabled. Users can also explicitly set
frontend.publicApiUrl if needed.
