CngxStepRejection

Slot directive for the rejection-decoration template on <cngx-stepper>. Discovered via contentChild; cascades through CNGX_STEPPER_CONFIG.templates.rejection before falling back to CNGX_STEPPER_GLYPHS.rejectionIcon.

Symmetric context shape with the upcoming tabs cngxTabRejectionIcon slot so consumer templates port directly between the two families.

<cngx-stepper>
  <ng-template cngxStepRejection let-failedIndex="failedIndex" let-originLabel="originLabel">
    <my-icon name="rollback" />
    @if (originLabel) {
      <span class="cngx-sr-only">Rolled back to {{ originLabel }}</span>
    }
  </ng-template>
</cngx-stepper>
