fix: only show test summaries on failure to reduce noise (#2435)

Changed JUnit report and Allure links steps from 'if: always()' to
'if: failure()' in both unit-test-jvm and integration-test-jvm jobs.
This prevents empty "0 ran, 0 passed, 0 skipped, 0 failed" summaries
from appearing when tests pass, while preserving debugging info when
tests fail. Aligns with recent change to gradle add-job-summary.
