chore: remove E2E testing infrastructure (#50)

* docs: update install docs to headlamp namespace (PRI-434)

- Update Helm/plugin install URLs from v0.2.4 to v1.0.0
- README: add pods/proxy RBAC scope, clarify controller is in kube-system
- docs/getting-started/*: update all download URLs to v1.0.0
- docs/deployment/helm.md: update install URLs to v1.0.0
- docs/architecture/overview.md: Headlamp Pod label → headlamp namespace
- docs/README.md: fix ArtifactHub URL
- CHANGELOG.md: add [Unreleased] entry

Note: driver/API-path references to kube-system are preserved
as they describe where the tns-csi controller workload runs,
not where Headlamp is installed.
