frontend: rotate example chips for broader story coverage

Swap Hoboken NJ and Miami Beach FL out, add NYC (350 5th Ave) and LA
(1 World Way) in. The previous set had three "coastal/Gulf, no Tier-1
city data" addresses telling variations of one story; the new set
covers four distinct FlutIQ strengths:

· Chicago Drexel — FEMA-gap + full Tier-1 pipeline
· NYC 5th Ave — NE urban, full Tier-1, CSO/sewer story
· LA World Way — full Tier-1, NRI wildfire + earthquake (multi-hazard, not flood)
· Houston Heights — outside Tier-1, NRI hurricane, graceful no-city-data
