Pin the retired Operator code and test the live HUD fallback

qa-radio cycles Minimal, off, on, then Tactical, so the HUD toggle must
restore a non-default layout, and expects that sequence instead of the
removed Operator step.

The share-link test pins the exact hudVariant codes, so dropping or
moving operator's reserved code fails it. A live IntelHUD test checks
that a retired Operator layout falls back to Tactical, and the Cyber
test stub themes from the normalized value.

The share-link table marks operator as retired, and the zh-CN glossary
drops the removed string.
