#0000 - Set up Kubernetes resources for Uptime Kuma deployment

Added YAML manifests to create the namespace, PersistentVolumeClaim, Deployment, Service, and Ingress for the Uptime Kuma application. Included configurations for TLS support, liveness probe, and a restore pod template for data management. These resources aim to facilitate scalable and secure application deployment.
