 *
 * Also defensively cleans up the pre-1.0.0 unprefixed `ntn_*` option/table
 * names (used only during this plugin's pending-review development period,
 * before every identifier was moved under the `ninetytwo_notify_` prefix):
 * if the site was never reactivated after that rename, the legacy names may
 * still be the only copy of the "delete on uninstall" opt-in and the data
 * itself, so both the new and legacy names are checked/removed here.
