Completes a batch upload by creating Asset records for all uploaded files. Each asset is created individually — a failure mid-batch does not roll back previously created assets.

## Important[​](#important "Direct link to Important")

* `signed_gcs_id` must be the exact value from `batch_upload_prepare`
* `batch_id` is optional but recommended — it releases the upload reservation
* For Backblaze multipart uploads, include `multipart_upload_id`
* Maximum 100 assets per batch
