Redmine

This patch adds a divider line at the bottom of the issue history. The purpose is to clearly separate the last comment from the issue action menu below it, so users don't accidentally delete the whole issue when they only meant to delete the last comment.

In Redmine 4.0.0, a border around the whole history was introduced for the same reason (#26662). However, in Redmine 6.1.0 the new design removed this border, bringing back the same risk that existed before version 4.0.0.

To address this, the patch adds a border-bottom at the end of the history. This makes it clear, as in Redmine 6.0 and earlier, that the menu is not part of the last comment. As a result, it prevents accidental issue deletion.
