fix: new comments not appearing after stimulus submission until manually refreshing the page.

Fixes spec/stimulus/turbo_spec.rb:42 failing in CI.
The Turbo spec was failing because new comments weren't appearing immediately after submission.
Added page reload after successful comment creation to ensure comment appears without manual refresh.
