feat(ui): polish across the app with new loaders, skeletons & animations

- ui/shimmer.tsx: reusable shimmer placeholder
- recipe-card-skeleton.tsx: skeleton grid for loading states
- CookingLoader: rebuilt as floating chef hat with orbiting sparkles
- RecipeDetailLoader: now a proper skeleton of the detail page
- PageTransition: smooth fade+lift on route change
- index.css: custom keyframes (shimmer, float, glow-pulse), thin
  scrollbars, :focus-visible, safe-area utilities
- RecipeList: skeleton grid, header with count, polished tabs,
  hover lift on cards, spring FAB on mobile
- Header: scroll-aware blur/shadow, animated active underline,
  auto-close mobile menu on navigation
- MainLayout: ambient blurred blobs in background, warm gradient
- Home hero: gradient pill badge with wobbling Sparkles,
  CTA with sliding sheen
- Login/Register buttons: brand gradient, inline spinners
- Profile: skeleton loading state instead of plain spinner
- RecipeForm streaming: glow halo behind image, blur-to-sharp reveal
