fix(dailies): fix PhotoSwipe CSS loading + restore expand button

Move PhotoSwipe CSS from per-entry assets.addCss() (runs after head is
committed) to a single <link> tag at block start. Restore the expand
button as the reliable mobile tap target — it dispatches a synthetic
click on the visible <a> slide, which bubbles to PhotoSwipe's gallery
handler. Merge dot sync into the single module script.
