fix(dump): pass --column-statistics=0 for MySQL 8 mysqldump on MariaDB

When the server is MariaDB but only MySQL 8's mysqldump is installed
(e.g. dockware/web), the dump aborted with "Unknown table
'COLUMN_STATISTICS' in information_schema (1109)".

 ### Changed
 
 - Requires Shopware 6.7 (`shopware/core ~6.7.0`); 6.6 stays on the 0.0.x line.
+- Administration: the list page is registered lazily, uses Meteor components (`mt-button`, `mt-banner`, `mt-progress-bar`) and stops polling on `beforeUnmount` (Vue 3).
+
+### Fixed
+
+- The admin build failed on a combined `import type` statement, so the Settings card never appeared.
+- Creating a dump failed on MariaDB when only MySQL 8's `mysqldump` was installed (`Unknown table 'COLUMN_STATISTICS'`); it now passes `--column-statistics=0` in that case.
