Chris Farhood 3d42bcee42 docs: correct namespace refs — driver is kube-system, not headlamp
Fix PRI-592. The tns-csi driver runs in kube-system (like most CSI drivers),
not in the headlamp namespace.

- CLAUDE.md: Driver namespace: headlamp → kube-system
- docs/architecture/overview.md: fix API paths for controller pod access
  from headlamp namespace to kube-system namespace

### Changed
- **docs: namespace references** — Updated all documentation, README, and ArtifactHub metadata to explicitly reference the `headlamp` namespace instead of generic "controller pod" language. RBAC examples now clearly scope `pods/proxy` access to `kube-system` where the tns-csi controller runs.
