Subject: [PATCH] feat(system): health-Endpoint liefert jetzt hostname + OS +
 kernel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- /system/health gibt zusätzlich hostname, os (PRETTY_NAME aus
  /etc/os-release) und kernel (/proc/version, ohne Build-Details) zurück
- Settings-Seite: SystemHealth-Interface erweitert, System-Info-Card
  zeigt Hostname, Betriebssystem und Kernel-Version an (conditional,
  nur wenn vorhanden)
- Nützlich beim Verwalten mehrerer Boxen — ohne SSH sofort sehen
  welches System gerade geöffnet ist
