Fixed
- Create and fix ownership of the
/backupsand/app/modulesvolumes inside the container. The Docker image only prepared/data, so when/backupsand/app/moduleswere mounted as named volumes they stayed owned by root and the app'snodeuser could not write backups or read installed modules. The container's permission fix now also skips itself gracefully when the container is started as a non-root user, which keeps it compatible with orchestrators that manage volume ownership themselves.
