Subject: [PATCH] Persist EuroOffice DATA_DIR as a volume

The euro-office image intends /var/www/euro-office/Data to be persistent
(its entrypoint stores the generated JWT secret and WOPI keys there and
prints 'Mount ${DATA_DIR} as a volume to persist it across restarts');
the generate-allfonts script also scans Data/custom-fonts for user-provided
fonts on every container start.

Without a volume, custom fonts and the generated secrets are lost whenever
the container is recreated on update. Mount a dedicated volume and include
it in backup_volumes (it is small: keys + fonts), unlike the reinstallable
documentserver volume.

The schema's path pattern is extended to allow capital letters because the
Data directory inside the image is capitalized.

Resolves the persistence gap discussed in #8493.
