Restore SearchPage.tsx react-hooks/refs seatbelt entry after revert

PR #88728 eliminated 31 react-hooks/refs violations in
src/pages/Search/SearchPage.tsx by switching from useState to useRef
moved into a useEffect, and the Auto-tighten eslint-seatbelt baseline
job removed the corresponding seatbelt entry in d791c21.

The revert in #89723 reintroduced those 31 violations but did not
restore the seatbelt entry, so lint now fails on main and blocks
deploys. eslint-seatbelt only auto-tightens, never auto-loosens, so
it cannot self-heal after a revert.

Restoring the deleted line unblocks main. When PR #88728 is re-rolled
the auto-tighten job will remove this line again.
