refactor(search): drop the applied-filter row above the results

The row repeated the search, local authority and school type above the
results list, and nothing else: no phase, distance, gender, sixth form,
admissions or faith. The filter bar already shows every one of them, in
its selects and More filters count on desktop and as removable chips on
phones, so the row was a partial second copy.
