Add log auto-clear setting (retention in days, 0 = off)

Neue Einstellung "Protokoll auto-leeren - Eintraege aelter als (Tage)".
0 = aus (alle Eintraege bleiben), >0 entfernt aeltere Eintraege.

- UserSettings.LogRetentionDays (Standard 0).
- Logger.PruneOlderThan(days): parst den Zeitstempel-Prefix je Zeile und
  entfernt zu alte; Zeilen ohne Zeitstempel bleiben erhalten.
- Ausgefuehrt beim Start, vor jedem Sync (Coordinator), beim Oeffnen des
  Protokolls und beim Speichern der Einstellungen.
- SettingsForm: NumericUpDown (0-3650).
