Audit «Вы искали» search history per TZ 4.1.9.5

TZ §4.1.9.5 requires session-scoped history ("в рамках одной сессии").
Migrate useSearchHistory from localStorage to sessionStorage so history
clears on tab close / page reload.

Add schema-validated get/set/deleteNs helpers to sessionStore in storage.ts
so the hook stays under no-restricted-globals constraints.

Fix hover style in SearchHistory.scss: TZ specifies голубая подложка with
white text/icon on hover — replace the near-white tint with the full blue.

Add TZ §4.1.9.5 assertion tests: session storage target, dedup + bump-to-top,
most-recent-first ordering, item types, empty initial state.
