Subject: [PATCH] Implement CSV fetching utility with retry logic in
 Mannschaften component

This commit introduces a new utility function, fetchCsvText, to enhance the fetching of CSV data in the Mannschaften component. The function includes a cache-busting mechanism and retry logic to improve reliability when retrieving data from the server. Additionally, it updates the loadMannschaften function to utilize this new utility, ensuring better error handling and consistent data retrieval. These changes contribute to a more robust application.
