ci: dump openidm logs after UI smoke tests

[vharseko]

The ui-smoke-tests workflow uploads openidm/logs only on failure, making post-run diagnosis from the Actions UI cumbersome.

Changes

• Added a final Print openidm logs step to the ui-smoke-tests job in .github/workflows/build.yml.
  • Runs with if: always() so logs surface on both pass and fail.
  • Enumerates files under openidm/logs sorted by mtime (oldest → newest) and prints each with a ===== <path> ===== header.
  • No-ops with a clear message if openidm/logs is absent.

- name: Print openidm logs
  if: ${{ always() }}
  shell: bash
  run: |
    if [ -d openidm/logs ]; then
      find openidm/logs -type f -printf '%T@ %p\n' | sort -n | cut -d' ' -f2- | while read -r f; do
        echo "===== $f ====="
        cat "$f"
      done
    else
      echo "openidm/logs directory not found"
    fi

Note: relies on GNU find -printf; the job pins runs-on: ubuntu-latest, so this is safe here.
