* fix(admin): use basePath for API fetches when urlPrefix is set
* fix(admin): drop duplicate iam-utils script on Groups page
* fix(admin): route topics page fetches through basePath
The Topics page missed two fetch() calls that still used root-relative
URLs, so create-topic and view-details still broke when -urlPrefix was
set.
