feat: Nova homepage, profile redesign, and legacy view system overhaul

Homepage
- Add HomepageService with hero, trending (award-weighted), fresh uploads,
  popular tags, creator spotlight (weekly uploads ranking), and news sections
- Add React components: HomePage, HomeHero, HomeTrending, HomeFresh,
  HomeTags, HomeCreators, HomeNews (lazy-loaded below the fold)
- Wire home.blade.php with JSON props, SEO meta, JSON-LD, and hero preload
- Add HomePage.jsx to vite.config.js inputs

Profile page
- Hero banner with random user artwork as background + dark gradient overlay
- Favourites section uses real Artwork models + <x-artwork-card> for CDN URLs
- Newest artworks grid: gallery-grid → grid grid-cols-2 gap-4

Edit Profile page (user.blade.php)
- Add hero banner (featured wallpaper/photography via artwork_features,
  content_type_id IN [2,3]) sourced in UserController
- Remove bg-deep from outer wrapper; card backgrounds: bg-panel → bg-nova-800
- Remove stray AI-generated tag fragment from template

Author profile links
- Fix all /@username routes in: HomepageService, MonthlyCommentatorsController,
  LatestCommentsController, MyBuddiesController and corresponding blade views

Legacy view namespace
- Register View::addNamespace('legacy', resource_path('views/_legacy'))
  in AppServiceProvider::boot()
- Convert all view('legacy.x') and @include('legacy.x') calls to legacy::x
- Migrate legacy views to resources/views/_legacy/ with namespace support
