This commit updates the Navigation component to replace links for "Über uns", "Geschichte", "TT-Regeln", "Satzung", and "Termine" with a consolidated "Inhalte" and "Sportbetrieb" section. Additionally, it removes the corresponding pages for "Geschichte", "Mannschaften", "Satzung", "Termine", and "Spielpläne" to streamline the CMS structure and improve content management efficiency.
