feat: add sort toggle to dailies and stories pages
dailies: reverse Twig output to ascending (matching trip default),
add feed-sort-bar above feed, add sort JS using [data-type] + appendChild.
stories: wrap heading in flex header row with sort button inline,
add sort JS targeting .story-card children of .stories-grid.
CSS: feed-sort-bar (right-aligned button above feed),
stories-listing__header (flex row, baseline-aligned), heading margin moved to header.
