orchestrai(!orc): show the ReportPortal link in the job summary (#689)

verdict.py already emits rp_url to $GITHUB_OUTPUT, but the pr-command job never
surfaced it. Give the verdict step id: results and add a Test summary step that
writes the RP link to $GITHUB_STEP_SUMMARY — mirroring test-playbooks-orchestrai.yml.
Runs on always() and rp_url is set even when the verdict fails, so the link is
there when a run needs inspecting. No PR-comment change.
