feat(orchestrator): multi-storage support for GCP and Azure providers

Both providers now support four storage backends via gcpStorageType / azureStorageType:

GCP Cloud Run:
  - gcs-fuse: Mount GCS bucket as POSIX filesystem (unlimited, best for large sequential I/O)
  - gcs-copy: Copy artifacts in/out via gsutil (simpler, no FUSE overhead)
  - nfs: Filestore NFS mount (true POSIX, good random I/O, up to 100 TiB)
  - in-memory: tmpfs (fastest, volatile, up to 32 GiB)

Azure ACI:
  - azure-files: SMB file share mount (up to 100 TiB, premium throughput)
  - blob-copy: Copy artifacts in/out via az storage blob (no mount overhead)
  - azure-files-nfs: NFS 4.1 file share mount (true POSIX, no SMB lock overhead)
  - in-memory: emptyDir tmpfs (fastest, volatile, limited by container memory)

New inputs: gcpStorageType, gcpFilestoreIp, gcpFilestoreShare, azureStorageType,
azureBlobContainer. Constructor validates storage config and warns on missing
prerequisites (e.g. NFS requires VPC connector/subnet).
