Rename search-history block 'Вы искали' → 'Ранее искали' (TIRREDESIGN-5)

Spec calls out the exact label change for the recent-searches sidebar
on Schedule and Online-Board start pages. RU was the literal 'Вы
искали' (You searched) — switch to 'Ранее искали' (Previously
searched), matching the section heading and the inline 'Ранее искали
в Онлайн-Табло' / 'Ранее искали в Расписании' captions. Other
locales already used 'Previous searches' / 'Search history' wording
and stay unchanged. Add 2-spec e2e seeding sessionStorage with a
valid history item and asserting the new label appears.
