Finalize an out-of-band upload after the file bytes have been PUT to the presigned URL. Verifies the stored object matches what was signed (size and content-type) and marks the attachment ready. Returns the attachment snapshot with its public variant URLs. Idempotent: confirming an already-confirmed upload returns the same snapshot.
