Why: the cockpit refresh reloaded overview and tree but left the node
detail at its old snapshot, so the 刷新对齐 banner persisted after
refreshing (DV-R05 wants every projection to advance). PanoramaNode now
refetches when the overview snapshotRevision advances. Scenario 4 also
scoped its tree clicks to the 验证主体报告 branch — the unscoped first
caret expanded an unrelated rdm-self doc.
Evidence: tsc clean, vitest green, build green (SELF); seven-scenario
rerun to be recorded on the Dev I4 card.
Impact: cockpit panorama + e2e spec.
