-- Remove legacy single-remote storage columns (superseded by #__mokosuitebackup_remotes).
-- Plain DROP COLUMN (no IF EXISTS): all columns are created by install.mysql.sql and
-- earlier updates, so they always exist here. `DROP COLUMN IF EXISTS` is a MariaDB-only
-- extension and errors on Oracle MySQL 8.x, which Joomla also supports.
