Research direction

Start by reproducing the failure at the occ app:enable end_to_end_encryption entry point using the reported Nextcloud 28.0.4.1 and Percona XtraDB Cluster 8.0 setup. Trace where the “json” database type is requested; done means the app enables without this error and the behavior is covered by an appropriate regression check.
