feat: Terminal Design an Landing Page Stil angepasst

- CommandCenterLayout: Brutalist/Technical Look (#020202 bg, Noise-Overlay, scharfe Ecken)
- Sidebar: Mono-Fonts, Border-Left für aktive Links, eckigere UI
- Top Bar: Minimalistischer, dunklere Farben, weniger Blur
- Notifications & Search Modal: Technischer Look mit schärferen Kanten
- User Card: Eckiger, weniger rund
- Konsistente Verwendung von white/[0.08] für Borders wie Landing Page
