gallery changes

Hero gallery: the slideshow on Home doesn’t open full screen. Only portfolio images do, as you asked.
Lightbox: it has no pinch-zoom.
Delete: removing an image still has no confirm step, same as before.
New dependency: drag-and-drop uses @dnd-kit, which I added to package.json.
Touch dragging: I couldn’t test it on a real phone. Mouse and keyboard dragging work.
Health test: src/app/api/health/__tests__/route.test.ts passes, but it prints unhandled rejections. Its prisma mock has no notificationDelivery, so getQueueHealth throws. That comes from the earlier “Remaining features” commit and I left it alone. It’s a quick fix if you want it.
