fix: status tools report a hook throwing during the write as partial_write

publish/unpublish/schedule/trash run their WordPress call through StatusWrite:
a throwing hook becomes WriteFailed (rollback incomplete, with post_id) and is
logged with result partial instead of surfacing as internal_error.
