.env on Netcup sets COMPOSE_FILE=docker-compose.yml:docker-compose.sablier-support.yml
but the file was never created, causing docker compose commands to fail
without explicit -f flag. Adds the missing override with Sablier labels for
encryptid services (matching the existing sablier-encryptid.yml pattern).
