FEAT(velero): configure minio

- for selective velero backup
Added pod annotation to exclude PVC data from Velero backups while
preserving MinIO resource definitions:
- backup.velero.io/backup-volumes-excludes: export

This prevents circular backup of the velero-backups bucket while
still backing up MinIO StatefulSet, Services, and configuration.

Note: MinIO bucket data (bucket, bucket-dev, velero-backups) will
NOT be backed up. Consider separate backup strategy for critical
bucket data if needed.
