Update CSV data fetching to use API endpoint in Mannschaften components

This commit modifies the loadMannschaften function across multiple components to fetch CSV data from the new API endpoint '/api/mannschaften' instead of the previous static file path '/data/mannschaften.csv'. This change enhances data retrieval consistency and aligns with the updated data management strategy in the application.
