v1.1.0: Druck-Optimierung, UI-Verbesserungen

- Drucklayout: kein innerer Rahmen, volle DIN-A4-Breite, @page-Regel
- Besucher-Spalte: zeigt keine 0 an wenn kein Wert eingetragen
- Beginn-Zeit synchronisiert automatisch die Ende-Zeit
- Hintergrundfarbe auf helles Blau (#EEF4FF)
- Listen-Tab und kompakte Vorschau mit weißem Rahmen
- Besucher-Spalte schmaler, Header als "Bes." abgekürzt
- Drucken-Button im Listen-Tab, Navigation bei Druck ausgeblendet
