fix: Verbindungs-Noise unterdrücken

- loadSettings() ruft connect() nur noch auf wenn ConnectionState
  NotConfigured oder Disconnected ist – verhindert den self-triggering
  Loop (pullSync → loadSettings → connect → Connecting → Connected → …)
- pullSync() erhält Parameter silent=true für den initialen Connect-Sync;
  zeigt kein 'Empfange Inventar-Update…' mehr beim bloßen Verbindungsaufbau
- Version 1.2 (3) → 1.3 (4)
