feat: Hero-Textschatten & Parallax, Speisekarte-Styling verbessern

- Hero: goldener Glow-Schatteneffekt auf "Graffen"-Schriftzug
- Hero: Parallax-Effekt für Titel und Subtitle beim Scrollen
- Speisekarte: mehr Whitespace (py-28/py-36), größere Abstände
- Speisekarte: ornamentale Trennlinien mit Stern statt border-b
- Speisekarte: Allergene unter Beschreibung, Tooltip für vegan/vegetarisch
- Speisekarte: Allergen-Button mit sichtbarem Rahmen
