fix: global usages follow the Theme Builder access (ruling Q17 M1)

GlobalUsages gets the Theme Builder access injected as a closure
(ThemeBuilderAccess::usageState(), wired at both construction sites through
DiviIntegration::globalUsages()). Theme Builder posts are named only while
the Theme Builder is visible to the account, otherwise only counted (also
in blocked_ids); a global edit that changes them needs canUse(), a writable
"Divi Theme Builder" group and edit_post. Without an injected access the
fail-safe default checks what canUse() checks. The duplicate
THEME_BUILDER_TYPES list gives way to DiviThemeBuilder::postTypes().
