[JavaScript][Integration] IPC files do not embed a valid IPC stream

### Describe the bug, including details regarding any error messages, version, and platform.

The format guarantees that each IPC file [embeds a valid IPC stream](https://github.com/apache/arrow/blob/bde6ac57ad943f5938506359de1b13fb85b4f8ea/docs/source/format/Columnar.rst) in order to allow readers to ignore the Footer, skip the file's leading magic, and reuse a stream reader.

https://github.com/apache/arrow/pull/43834 adds validation of the embedded IPC stream and files written by JavaScript fail. When writing IPC files JavaScript seems to [omit the stream's Schema message](https://github.com/apache/arrow/actions/runs/10565413633/job/29269867382?pr=43834#step:9:26987) rendering the file unreadable by a stream-only reader.
