ci: blackbox test impromentts

A mutated zli config could be the cause of https://github.com/project-zot/zot/actions/runs/21560982825/job/62141227950

1. show zli configuration after cve.basts finishes running
2. ensure the zli config is removed in between test files
3. ensure teh zli configs use different names, not "main"
