Fix changelog entry ordering in multi-project show command (#6)

* Fix changelog entry ordering in multi-project show command

Entries were displayed newest-first instead of oldest-first when
showing multiple projects. Changed the sort key in
_render_entries_multi_project() from -ts to ts to sort entries
ascending by date, ensuring consistency with single-project display
and placing the newest entry at the bottom of the table where users
expect it.

* Ensure consistent entry ordering in multi-project show command

The multi-project show command now displays entries in chronological
order (oldest first), matching single-project behavior and user
expectations. Previously entries were sorted newest-first, creating
an inconsistency in the application's sorting behavior.

+The multi-project `show` command now displays changelog entries in chronological order, with the newest entry at the bottom of the table where users expect it. Previously, entries were sorted newest-first, which was inconsistent with single-project behavior and user expectations. This brings the multi-project display in line with the rest of the application's sorting behavior.
