Make TestNG custom listener evidence work automatically

[baev]

Context

Starting with TestNG 7.5, TestNG changed listener callback ordering in a way that could close the Allure test result before custom ITestListener callbacks added their evidence. This PR makes Allure handle that ordering automatically, so users on TestNG 7.5+ can keep custom listeners registered with @Listeners or testng.xml and still get steps and attachments on the correct test case.

Example: a custom ITestListener.onTestFailure(...) callback that calls Allure.addAttachment("Screenshot on failure", "image/png", screenshotStream, ".png") now attaches that screenshot to the failed test automatically.
