local testing with Redis throw TTL not supported by local storage

### 🐛 Describe the bug

```
2026-06-12 01:08:36,733 - adapter.py:286 - finalize_job_output_data - INFO - {"job_id": "f93f373d-69bb-4fe5-8e93-458275253bfb", "launched": 500, "total": 500, "event": "Finalizing job output data using metastore keys", "logger": "aibrix.batch.storage.adapter", "level": "info", "timestamp": "2026-06-12 08:08:36 UTC"}
```

### Steps to Reproduce

```
kubectl port-forward svc/redis 6379:6379
kubectl port-forward svc/minio 9005:9000 9001:9001

npm run dev
./bin/console --dev-mode -v=2

poetry run python -m aibrix.metadata.app --host 0.0.0.0 --port 8090 --enable-k8s-support

```

### Expected behavior

it should not have such warnings

### Environment

nightly

Start at adapter.py around line 286 and inspect how job output finalization handles Redis TTL with local storage. Reproduce the warning using the listed kubectl, npm, console, and Poetry commands, then confirm the local-storage path no longer emits the unsupported-TTL warning.
