GUI ans Mockup-Design angepasst (GEFIM-Branding)

- GEFIM-Farbwelt aus dem Mockup als shadcn-Theme: Violett #5d52a3 als
  Primärfarbe, Magenta/Hellblau-Akzente, Ink-Text, #f5f6fa-Hintergrund,
  Verlaufs-Utilities (bg-grad, bg-grad-soft), Karten-Schatten
- Fonts Poppins (Überschriften/Buttons) + Open Sans (Text), self-hosted
  über next/font — kein Google-CDN-Aufruf zur Laufzeit (DSGVO)
- Sidebar mit extrahiertem GEFIM-Logo (public/gefim-logo.png), aktive
  Navigation in Violett wie im Prototyp
- Sticky Topbar mit globaler Suche (leitet vorerst auf die Asset-Suche),
  Nutzer-Info und Verlaufs-Avatar mit Initialen; Logout in die Topbar
- Primär-Buttons mit Verlaufshintergrund, Level-Badges als Pillen in
  Mockup-Farben, Login-Seite im GEFIM-Look
- Dashboard im Mockup-Stil: KPI-Karten (Assets, Prozesse, kritische
  Prozesse, Risiken-Platzhalter) und Letzte-Aktivitäten-Feed aus dem
  echten Audit-Log
