feat: Switch to Astro SSR with API routes support

- Changed output: 'static' → 'server' in astro.config.mjs
- Added @astrojs/node adapter for dynamic serving
- Updated Dockerfile to use astro preview (not serve package)
- Fixed package.json dependency conflicts
- All API routes will work (privacy consent logging)
- Static pages still work

Now includes BOTH:
- ✅ Static pages (product pages, blog)
- ✅ Dynamic API routes (cookie consent logging)
- ✅ Admin dashboard with database access
- ✅ Fixed host restrictions
