Add version badge to sidebar footer showing installed vs latest version, fetched from /api/nixserver/system/version. Badge shows green when up to date or amber with target version when an update is available. Upgrade button triggers POST /api/nixserver/system/upgrade which spawns scripts/update.sh detached (git pull + npm install + prisma migrate + build + restart). Response is returned before the service restarts so the client receives confirmation. Panel comes back online in ~60 s.
