feat(scheduler): NTP-Sync-Alert — warnt wenn chrony keine Zeitquelle hat — v1.1.109

Browse Source 
- runNTPSyncCheck() läuft alle 10 Minuten: ruft chronyc tracking auf,
  prüft ob Stratum 0 / ≥16 oder Reference ID 00000000 — feuert
  Warning mit Fix-Hints (1h dedupe)
- Initial-Check absichtlich NICHT beim Boot, da chrony nach dem Start
  einige Sekunden zur ersten Synchronisation braucht
- ntp.unsync-Trigger in beiden i18n-Dateien dokumentiert
