fix: Respect collage orientation setting in layout previews

- Read orientation from config (landscape/portrait)
- Pass orientation to loadCollageLayoutFromJson()
- Previews now use correct template files based on admin setting
- Portrait: 1200×1800 (2:3), Landscape: 1800×1200 (3:2)
- ViewBox and photo positions adapt automatically
