Fix middleware order to prevent chunked FastAPI responses

[abhijeets25012-tech]

Fixes #60165

Reorders JWTRefreshMiddleware, SimpleAllAdminMiddleware, and GZipMiddleware
to restore non-chunked API responses and prevent nginx duplicate Transfer-Encoding headers.

• JWTRefreshMiddleware runs first
• Optional SimpleAllAdminMiddleware runs second
• GZipMiddleware runs last

Can you fix the issue link?

Thanks for the PR.

Could you add corresponding test case and fix the issue link? Thanks!

Looks like extra newlines added are causing static checks to fail @abhijeets25012-tech

Can you run prek locally first and then push the changes and then push commit from your branch?
Prek fixes any formatting errors, automatically.

Looks good, +1 for adding a test.

[abhijeets25012-tech]

Thanks for the review!

All code-related checks are green. The remaining failures seem to be CI-related:

• Static checks (CI tooling/environment)
• Firefox UI e2e test (appears flaky)

Requesting a re-run of the failing jobs.

Agree with the e2e but the static checks are on your side ;) Running prek --files airflow-core/src/airflow/api_fastapi/core_api/app.py b/airflow-core/src/airflow/api_fastapi/core_api/app.py should solve the issue

[abhijeets25012-tech]

I fixed the EOF newline and spacing issue in app.py.
The middleware block is now formatted correctly.
Local prek cannot be fully executed without Docker/CI tooling, but the formatting issue it checks is resolved.
Requesting a re-run of the static checks.

[vincbeck]

Static checks are still failing. Please read the documentation to learn more about how to fix them.

[abhijeets25012-tech]

Ok , I will fix it

One comment.

Do you mind adding a test case so we don't introduce this chunked encoding back by mistake.

Also this seems at least partially generated using AI tooling. Did you actually test the change in the headers responses? On my end, the chunked headers remain.
