fix(news): style Sources lists with guide-linklist across articles

The Sources sections on the Welcome Days, accommodation-search and
Ad futura scholarship articles used bare <ul>/<ol> lists, which rendered
as default bullets/numbers with plain blue links instead of the site's
standard source-list style (chain icon, teal links, row dividers).

Add class="guide-linklist" to the Sources lists (converting Ad futura's
<ol> to <ul>) in the content/ source markdown and the generated en/mk/si
pages, matching the Student Welcome Guide. Edits scoped to the affected
articles to avoid unrelated build-tool reformatting churn.
