feat(dailies): replace custom lightbox with PhotoSwipe v5

Drops ~80 lines of fragile custom lightbox JS/HTML/CSS in favour of
PhotoSwipe v5 loaded from CDN. Slides are now <a> tags (the pswp-gallery
children) which always fire click events on iOS even inside scroll
containers — the root cause of the mobile tap issue. Pinch-to-zoom and
swipe-to-dismiss come for free. Dot sync kept as a separate vanilla JS
block.
