M6.5: enroll lasuite-docs (recipe #5, multi-service + S3/MinIO) — install verified green

9-service stack (frontend/backend/celery/y-provider/docspec/postgres/redis/minio/nginx) converges
9/9 and serves the SPA; install 2 passed on host. Root-caused a deploy timeout: cold-pulling ~9
large images exceeds abra's default 300s convergence TIMEOUT -> bumped to 900 via EXTRA_ENV (the
generic per-recipe mechanism, no harness surgery). upgrade/backup use a postgres marker (docs/docs)
exercising the pg_backup.sh DB-dump hook; verifying next.
