Fix CI/pulumi blockers and document test suites with latest PASS results.

Stabilize node status, cluster-wide Ceph OSD ids, and QEMU cpu utilization so
status/list no longer 500 on model strings; align pulumi defaults to pve1;
add bilingual testing docs with the 2026-07-18 ci-all + pulumi-tests pass.
