feat(fc-devicemgmt): add Kubernetes deployment manifests (#1)

Sprint 8 IMPL lane Cx-5: fc-devicemgmt K8s manifests (rebased onto main 2026-05-18; 13 files, +944).

Namespace + Web Deployment (replicas:2, MySQL backend) + Operator Deployment (replicas:1, KubeOps leader-elect) + Service + Certificate (step-ca-acme ClusterIssuer) + Traefik IngressRoute (devices.iamworkin.lan internal) + ServiceAccount + ClusterRole + ClusterRoleBinding + NetworkPolicy (CNI DNAT-aware backend ports) + OnePasswordItem (5-field consolidated) + ArgoCD Application bootstrap shape + lint coverage.

Follow-ups (not merge blockers):
- localhost/fc-devicemgmt-{web,operator}:v20260512-cx5 must be imported to all 3 RKE2 nodes; pods will ErrImageNeverPull until imported.
- 1Password vault item 'FlowerCore DeviceManagement Runtime' must be created with 5 fields before pods can start.
- DNS devices.iamworkin.lan -> 10.0.56.200 already present.
