fix(i18n): WireGuard QR/.conf Buttons + Backend 'Upgrade gestartet' → Englisch

- Servers.tsx: 'QR' und '.conf' Button-Labels in t() überführt (wg.peer.qr/conf)
- system.go: hardkodierter deutscher API-Response-String 'Upgrade gestartet'
  → 'upgrade started' (API-Responses sollen immer Englisch sein)
