Fixes #16340
Continuing the work of #16340

Previously the implementation relied on a combination of the default field values being and
model_dump_json(exclude_unset=True). This led to bugs such as the "type" field missing from the response.

The behavior of the OpenAI API is to set the "id" and "type" fields only in the first Delta object.

The purpose of this commit is to make all the places where these fields need to be set explicit.

👋 Hi! Thank you for contributing to the vLLM project.

💬 Join our developer Slack at https://slack.vllm.ai to discuss your PR in #pr-reviews, coordinate on features in #feat- channels, or join special interest groups in #sig- channels.

Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can either: Add ready label to the PR or enable auto-merge.

🚀

@iGmainC , did you get a chance to test on your side? The CI tests are passing now.

I briefly tested my scene and it seemed to be ok.
