Subject: [PATCH] fix: production API URL, k8s single replica, health probes

- Change API_URL default from localhost:4000 to empty string (relative URLs)
- Set VITE_API_URL="" explicitly in Dockerfile frontend build stage
- Reduce k8s replicas to 1 (SQLite + ReadWriteOnce PVC)
- Add liveness and readiness probes targeting /health endpoint
