v0.67.6

Fixed

• Docker/Podman: BACKUP_DIR in docker-compose.yml and podman-compose.yml is now hardcoded to /backups in the container's environment: section. Previously, setting BACKUP_DIR=./backups in .env to control the host-side volume mount source would also inject that host path into the container, where it does not exist — causing backups to fail silently. The container-side mount target is always /backups (fixed in volumes:), so the env var is now set unconditionally to that value.
