feat(k8s): add Kubernetes Helm chart for emailks service

- Create Helm chart structure with Chart.yaml and values.yaml - Add deployment template with container configuration and environment variables - Implement service template for gRPC port exposure - Add service account template with security configuration - Include horizontal pod autoscaler template for scaling capabilities - Add helper templates for naming and label management - Configure SMTP settings as configurable parameters in values.yaml - Set up resource limits and requests for container performance - Implement liveness and readiness probes for health checks - Add support for existing secrets and custom configurations
