/**
 * RevertController — the "revert to old website" AJAX endpoint.
 *
 * Moved from modules/full-site-import/Ajax/ (2026-07-23, the split-modules
 * follow-up): revert reads FINISHED-import artifacts (`__templately_*` backup
 * options via FSI's `Utils::get_backup_options()`, `templately_fsi_imported_list`)
 * but shares no live import state with the runner pipeline — a real module
 * boundary. Still registered through FullSiteImport's nonce/capability AJAX
 * wrapper, via its `templately_fsi_ajax_handlers` filter seam (see module.php);
 * the `wp_ajax_templately_pack_import_revert` action name is unchanged.
