feat(dashboard): Kacheln und Karten verlinken auf ihre Bereiche

Die Statistik-Kacheln springen jetzt zu ihren Zielen. Organisationen und
Nutzer zur Organisations-Verwaltung, Aktive Lizenzen zum Lizenzen-Tab,
Vorfälle öffnen den Monitor in einem neuen Tab (im Portal gibt es keine
Vorfalls-Seite). Die Karte "Bald ablaufende Lizenzen" führt zum
Lizenzen-Tab, "Letzte Aktivität" zum Audit-Log. Hover-Optik mit
Gold-Rahmen und Chevron, bedienbar auch per Tastatur (Enter/Leertaste).
