- compose.yaml: rewrite db-backup to use heredoc script instead of inline
cron command, fixing date escaping and adding temp-file pipeline for
reliable error detection
- compose.yaml: fix pipefail issue by writing pg_dump to tmp file before
compression and rotation
- restore.sh: pass PGPASSWORD explicitly via docker compose exec -e
- restore.sh: use ". .env" with set -a/+a instead of fragile xargs export
