fix: correct field help text layout on Django 5.2

[pandafy]

After commit 7537fcb, field help text in Django 5.2 were rendered inside the flexbox container, causing it to appear on the same line as the field. This broke Django’s default layout convention, where help text is displayed below the field.

This patch moves the help text outside the flexbox container, restoring the expected layout.
