Tests: align cek content-page names with injector output

Load sx/sx/geography/cek/ recursively so content/demo/freeze index.sx
pages bind as ~geography/cek/{content,demo,freeze}. Update docs.sx
cek-page dispatch + test-examples cek:content-pages suite to reference
those real names (were stale ~geography/cek/cek-content etc.).
