fix: Ensure integration test required checks fail on chunk failures

[Officeyutong]

What problem does this PR solve?

Issue Number: close #xxx

Problem Summary:
The integration-test workflows run the real tests in matrix jobs named Run tests (chunk N), then keep the historical required-check names as final aggregate jobs:

• ci_integration_tests_ubuntu
• ci_integration_tests_macos
• ci_integration_tests_windows

Those aggregate jobs depended on the matrix test job but used the default success condition. If any matrix chunk failed, the aggregate job was skipped. GitHub Actions reports skipped jobs as successful, even for required checks, so branch protection relying on the historical check names could allow a PR to merge despite failed integration-test chunks.

What is changed and how it works?

Proposal: xxx

What's Changed:

Run the aggregate required-check jobs with always() and explicitly inspect needs.test.result.

If the matrix test job result is not success, the aggregate job now exits with failure. This preserves the old required-check names while ensuring they accurately reflect the real integration-test result.
