Native MapLibre — non-OpenMap map widgets (#2273)

These widgets each own a small standalone map, separate from OpenMap. All three now run native MapLibre on our bb-default vector style — Leaflet is gone from the bundle entirely. This page exists so they can be exercised against this tree's build; the roster/brokers/details pages otherwise only live under /preview/, which points at the CloudFront preview artifact.

1. <mbb-location-map> via Office Roster — multi-marker, numbered pins

2. <mbb-location-map> via Brokers — single-marker mode

3. <mbb-search-details> — property details map (toggle to the Map tab)
