[ZEPPELIN-6063] Fix delay in paragraph results rendering in new UI

[tbonelee]

What is this PR for?

In new UI, the results are rendered only after some interactions, such as a click on the other paragraph.

This PR addresses the issue by ensuring immediate rendering of the results when they are set in the ngAfterViewInit lifecycle hook. Previously, markForCheck() was used after setting this.innerHTML, which scheduled the component to be checked in the next change detection cycle but did not trigger an immediate update.
This has been changed to detectChanges() to force an immediate change detection, ensuring that the results are rendered right after they are set, without needing further user interaction.
