Fundament: Branding Craftvia

- Farb-Tokens laut Brandbook §11.4 (Lotsenblau, Signalorange, Graphit, Hafengrau,
  Stahlgrau, Zink, Funktionsfarben) in globals.css + src/lib/brand.ts; helles Theme
- Inline-SVG-Logo src/components/brand/craftvia-logo.tsx (horizontal/signet,
  color/mono/reversed, App-Icon-Kachel, optionale Tagline); Certvia-/GEFIM-Logos entfernt
- Favicon/PWA-Icons aus dem Signet erzeugt (scripts/generate-brand-icons.ts),
  site.webmanifest (Craftvia, theme_color #082E5B)
- Inter selbst gehostet (next/font/local, lokale OFL-Datei), Open Sans/Poppins entfernt
- Metadaten, WebAuthn-RP-Name, Mail-/Dokument-CD auf Craftvia umgestellt
- docs/craftvia/BRANDING.md ersetzt docs/BRANDING-CERTVIA.md
