Enable MinIO S3 storage with internal Docker network endpoint

Changes:
- Uncomment S3 storage configuration (lines 58-66)
- Set S3 endpoint to http://minio:9000 (internal Docker network)
- Configure S3 force path style for MinIO compatibility

This replaces the external endpoint (https://s3.b28.dev) with direct
container communication, avoiding Cloudflare Tunnel latency and
SSL/redirect issues.
