All People Groups: find its data when a partner page embeds the script

With no assetsBase in the profile-config, the map fell back to '/assets' and
asked the host site for people-groups-slim.json. That is a 404 on any partner
page, so a script embed drew a basemap with no groups on it. It now resolves the
base through resolveAssetsBase(), the same path the other bundles use, which
finds the asset pool inside the tree the script came from.

Measured with the tree served under /plugin-assets/doxa-maps/ and a partner
page on the same host: main requested /assets/... and got 404; this build
requested /plugin-assets/doxa-maps/assets/... and got 200, drawing all 12,379
locations. The leaf page and the Research Gallery tab load on both builds.
