Following up on RHEL-77812, we now integrate dpdk's image mode tests into our CI pipeline so they run after each merge request or daily.

We also need to make sure tests results are uploaded to Polarion per RHELMISC-8899's requirement. This traceability is mandatory to demonstrate readiness for RHEL 10 image mode GA.

Acceptance criteria:

Given we have a CI pipeline for dpdk,

When a merge request is created or a nightly build is triggered,

Then the Image Mode test suite (validated in RHEL-77812) runs on x86_64 and aarch64, any failures generate automatic alerts and all results (pass/fail) are synced to Polarion.

Definition of Done:

• The Image Mode test suite is integrated into the CI pipeline, running automatically after each merge request or on a scheduled job.
• All test results (pass/fail) are uploaded to Polarion
