fix: push-first strategy in build_image to avoid losing latest tag

The push_image function deleted the existing manifest before pushing
(Gitea #31964 workaround). When push failed for other reasons (HTTP
500), the old tag was lost, breaking all CI jobs using that image.

Now tries push first, only deletes+retries on "already exists" error.

Closes DEVX-159
