/**
 * PackInfoController — independent AJAX endpoint handler extracted from FullSiteImport.
 * Registered through FullSiteImport's nonce/capability wrapper (action names unchanged).
 *
 * Both handlers here are now DEPRECATED SHIMS: the primary transport moved to REST
 * (`REST\PackInfo` = GET /import/info, FR-018; `REST\GlobalSettings` = POST
 * /import/global-settings, FR-018/B8). These ajax actions are kept only so already-cached
 * old frontend bundles keep working. The upstream fetch is shared via `PackInfoFetcher`.
