Prepares the S3StorageService surface for the MinIO upload migration:
- UploadStream(ctx, io.Reader, key, contentType, size) — streams bytes
via the existing manager.Uploader (multipart, 10MB parts, 3 goroutines)
without buffering the whole body in memory. Tracks can be up to 500MB;
UploadFile([]byte) would OOM at that size.
- GetSignedURL(ctx, key, ttl) — presigned URL with per-call TTL, decoupling
from the service-level urlExpiry. Phase 2 needs 15min (StreamTrack),
30min (DownloadTrack), 1h (transcoder). GetPresignedURL remains as
thin back-compat wrapper using the default TTL.
No change in behavior for existing callers (CloudService, WaveformService,
GearDocumentService, CloudBackupWorker). TrackService will consume these
new methods in Phase 1.
