fix: skipped failing bailedout tests in CI

[Revolyssup]

The test here https://github.com/apache/apisix/actions/runs/16511586539/job/46694453675
failed due to invalid configuration but in case of Bailout, the tests is considered successful. This change asserts and finds for the bailed out test and fails CI if any test was bailed out.

The following tests fail after the changes in script in this pr https://github.com/apache/apisix/actions/runs/16519080359/job/46716551717
https://github.com/apache/apisix/actions/runs/16519816286/job/46718888226?pr=12462#step:16:236

I have modified the above tests to finally pass.

The doc says
"By default the test scaffold treats NGINX server startup failures as fatal errors in running the tests. The must_die section, however, turns such a failure into a normal test checkup."

If you have just one test then it holds true. But when even one test passes and subsequent test has invalid config then TEST IS CONSIDERED PASS.

WHen invalid configuration was passed in Test 1 (As expected the Bailout is considered total test failure)

Test run interrupted!
