feat: Banner-Check — Historie, persistentes Ergebnis, E-Mail-Report

1. localStorage Persistenz: URL, letztes Ergebnis, Historie (30 Eintraege)
2. Historie: Zeigt URL, Datum, Provider, Violations, Prozent
3. Letztes Ergebnis bleibt nach Tab-Wechsel/Reload sichtbar
4. E-Mail-Report: HTML-formatiert mit Violations + Hints an mailpit
5. Email-Status Anzeige im Frontend
