Home hero: replace filter dropdowns with a search-engine box (+ live typeahead)

The hero is now a single big search box → /Search (the rich, ranked,
highlighted search across shifts/jobs/applicants), with popular-search
chips. Typeahead is generalized to any form[data-suggest], so the hero box
shows the same instant highlighted dropdown as the header pill.
