fix(bootstrap5): add gap-2 between status alert icon and message text

Removing justify-content-between left the icon and text touching with no
spacing after handleNotification rerenders the alert into two flex
children. Add gap-2 (0.5rem) on the parent so they get a small visual
break consistent with Bootstrap 5 alert conventions.

The deleted-paste case (icon + text inline inside the inner div, plus the
"Start over" button as the second child) keeps its original spacing
because PHP_EOL provides the icon-text separation; gap-2 only adds 0.5rem
between the inner div and the right-aligned button, which reads cleanly.
