feat: add Xpeditis logo as favicon and improve metadata

Add site favicon and enhance metadata for better SEO and social sharing:
- Added app/icon.svg from existing logo for browser tab icon
- Enhanced metadata with Open Graph and Twitter card support
- Created manifest.json for PWA support
- Added metadataBase for proper social image resolution
- Updated .env.example with NEXT_PUBLIC_APP_URL

The Xpeditis logo (blue background with cyan X) now appears in:
- Browser tabs (favicon)
- Bookmarks
- Mobile home screen (PWA)
- Social media shares (Open Graph)

Configuration for different environments:
- Dev: NEXT_PUBLIC_APP_URL=http://localhost:3000
- Preprod: NEXT_PUBLIC_APP_URL=https://app.preprod.xpeditis.com
- Prod: NEXT_PUBLIC_APP_URL=https://xpeditis.com
