refactor(web-test): этап B.5.1 — safeClick хелпер вместо 3 копий pointer-events retry

В fillReferenceField, clickElement и DLB-ветке selectValue был один и тот же
паттерн: page.click → catch 'intercepts pointer events' → force-click →
catch снова → Escape + retry. Три копии (плюс одна с dismissPendingErrors).

core/helpers.mjs (новый): safeClick(selector, { timeout, dismissErrors }).
Экономия ~60 LOC дублей. Поведение 1-в-1 (dismissErrors:true только в
fillReferenceField — там единственное место, где исходно было).
