Fix(io): track RDMA notification completions in transfer status

[amd-dlimpus]

Motivation

Mori can use a separate network message to tell the remote side that a data transfer has finished. Before this change, a transfer could be marked successful as soon as the data write completed, even though that completion message was still in progress.

That created a race: the sender could report success, but the receiver might never get the completion message if that later send failed. In that case, both sides could disagree about whether the transfer was actually complete.

Technical Details

This change makes the data write and its completion message part of the same tracked operation.

The transfer is now marked successful only after both pieces have completed:

• the data write
• the completion message sent to the remote side

If sending the completion message fails, the transfer status is updated as a failure instead of being left as a prior success.

The implementation reuses the existing submission tracking path for completion-message sends, so these sends are handled the same way as other network work requests. A small fallback remains for older completion-message identifiers.

Test Plan

Added a focused C++ regression test that verifies:

• completing the data write alone does not mark the transfer successful while the completion message is still pending
• a completion-message failure is not overwritten by a later success update

Also ran editor diagnostics on the touched files.

Test Result

Editor diagnostics passed.

A local C++ syntax check could not complete in this environment because a required Boost header is missing:
boost/predef/other/endian.h.
