Subject: [PATCH] fix(k8s): correct port configuration for Next.js 3000 port
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix 502 Bad Gateway error - application was configured to listen on port 80
but Dockerfile specifies port 3000 for Next.js.

Changes:
- Updated deployment.yml: containerPort 80 → 3000 (both prod & alpha)
- Updated service.yml: targetPort 80 → 3000 (both prod & alpha)
- Added image registry suffix: hosting-frontend → hosting-frontend-prod/alpha
- Added environment variable: NEXT_PUBLIC_API_URL
- Added health checks: livenessProbe and readinessProbe
- Added protocol: TCP explicit declaration

Benefits:
- Fixes 502 Bad Gateway errors from Cloudflare
- Proper port mapping: Ingress 80 → Service 80 → Pod 3000
- Health checks enable Kubernetes to detect pod issues
- Environment variables passed at deployment time

Deployment Flow:
  Client → Cloudflare → Ingress (traefik:80) → Service (port:80) → Pod (3000)
