Replaces the flat news list with a D8-style two-pane layout: a filterable
list on the left (All/Drafts/Scheduled/Published chips with counts) and a
preview of whichever item is selected on the right, reusing the same
article/photos/publish markup news_detail.html already had (now factored
into _news_preview.html so both pages share it). Adds an NL/EN language
toggle to the article preview -- the club's two content languages are now
switchable in place, with a fallback note when a translation is missing,
instead of a separate "English" card that only appeared once translated.
The standalone news_detail.html permalink page is unchanged behaviourally.
