feat(deploy): add k3s deployment foundation and complete offline images

Introduce a self-contained kustomize stack under deploy/k3s covering
namespace, config, placeholder secrets, infra StatefulSets, app
Deployments/Services, migration and minio-init Jobs, and Traefik
Ingress for both tenant and ops hosts. Add Dockerfile.ops-web so the
operations frontend can ship as an nginx image, and extend the offline
package script to build and bundle ops-api, kol-assist-worker, and
ops-web alongside the k3s manifests. Wire the new ops/security knobs
through .env.example and the compose stack.
