> Create presigned preview URLs for several S3 paths in a single request.

post /prod/v1/files/preview/batch

Create presigned preview URLs for several S3 paths in a single request.

Accepts up to 100 paths in `s3Paths`. Results are returned in
request order, each echoing its `s3Path` so callers can map URLs back to files.

All-or-nothing: if any path is invalid the whole request fails — no partial results.

Use `POST /v1/files/preview` for a single path.
