fix(k8s): rename deployment/service/ingress to news-site

Align new manifest names with the live deployment so CI replaces
the existing news-site deployment instead of creating a parallel
signalledger one.

Changes:
- deployment name: signalledger -> news-site
- service name: signalledger -> news-site
- ingress name: signalledger -> news-site
- selector labels: app.kubernetes.io/name -> app: news-site
- ingress backend service: signalledger -> news-site
- ingress hosts: add news.claw.jopdorp.nl, keep signalledger.nl + www
- TLS secret: signalledger-tls -> news-site-tls (existing live secret)
- CI rollout target: deployment/signalledger -> deployment/news-site
