Multi-Domain-Asset-Infrastruktur: geteilte Vite-Konfiguration und DomainAssetContext

- vite.shared.js als gemeinsame Quelle fuer Ports, Hot-Files, HMR-Hosts
  und CORS-Origins der beiden Vite-Builds (Portal/Web)
- App\Support\DomainAssetContext kapselt die Vite-Build-Directory-
  Konfiguration pro Domain (ThemeServiceProvider + Auth-Layout nutzen ihn)
- Tailwind-Portal-Content-Globs auf die tatsaechliche View-Struktur gezogen
- Dev-Beispiel-Routen + Tests (DomainAssetContextTest, DevExampleRoutesTest)
- Aufraeumen: versehentliche Leerdatei dev:web entfernt
