toaster: fix layout for command-line builds in recent builds area

Command-line builds were displayed incorrectly, so that the
HTML elements for other builds were being "consumed" by the
command-line build elements due to incorrect positioning of
element end tags.

Fix by ensuring end tags close elements in the right places.

As the indentation was all over the place in the most recent
builds section template, it was almost impossible to see what the
problem was. So that was fixed, too.
