Subject: [PATCH] Update CSV export to use semicolons as separators for better
 Excel compatibility

Modify the CSV generation logic in server/routes.ts to use semicolons (;) instead of tabs (\t) as delimiters. This change addresses issues with CSV files not being properly tab-delimited in certain spreadsheet applications, particularly in French locales, ensuring each row is correctly parsed.
