feat: add Woodpecker CI pipeline, Dockerfile, and Helm chart for K8s deployment

Static site served via nginx-unprivileged on ITSH cloud (tenant-2). Pipeline: lint → docker build+push to somegit.dev → helm deploy. Includes HTTPRoute with TLS, HTTP→HTTPS redirect, health probes, and hardened security context.
