Add comprehensive layout and styling controls including header layout options (standard, centered, left), content width settings (contained, wide, full), and card shadow levels. Update all theme presets with these new settings. Replace placeholder images with real Unsplash product and category images for more realistic previews. Add announcement bar and sticky header toggle options for enhanced header customization.

- Add Google Fonts link to root layout for typography presets
- Add data-mood, data-typography, data-shape, data-density attributes to preview-frame
- Create theme-layer2-attributes.css with attribute-based CSS from demo
- Move theme CSS files from priv/static/css to assets/css for proper compilation
- Update CSS import order (primitives → layer2 → semantic)
- Add 'css' to static_paths to serve theme CSS files
This fixes the issue where theme controls updated the database but didn't
visually affect the preview. The demo's attribute-based CSS system is now
properly integrated with the Phoenix LiveView implementation.
