fix(test): landscape gate bounds the promotion count instead of pinning 3

Browse Source 
The alt-hinted image promotion rides the per-render measurement race
already filed in TODOS (2-vs-3 landscape pages on renders seconds
apart — CI receipts from PR #2721, now reproduced locally). Pin the
two deterministic promotions as the floor and the three promotable
blocks as the ceiling (anything above 3 means the veto leaked); the
veto/portrait assertions remain exact.
