Implementiere umfassendes Logging-System für WOL-Ereignisse

- Neue Log-Tabelle in der Datenbank
- Automatisches Logging bei WOL-Button-Klicks
- Dedizierte Logs-Seite mit Bootstrap-Design
- Tooltips mit letzten 5 WOL-Ereignissen pro PC
- API-Endpunkte für Log-Verwaltung
- Einheitliches Design zwischen Haupt- und Logs-Seite
- Vollständige Dokumentation des Logging-Systems
