chore: update favicon to use full Xpeditis logo

Replace the icon with the full Xpeditis logo (logo-black.svg) as requested.
Updated references in:
- app/icon.svg (favicon)
- app/layout.tsx (metadata and social cards)
- public/manifest.json (PWA icon)

Note: The full logo (1875x1699px) will be scaled down in browser tabs.
Consider creating a square optimized version for better display in small sizes.
