- Add deleteScript method to ScriptDownloaderService (both .ts and .js) - Add deleteScript API endpoint to scripts router - Add delete button to ScriptDetailModal with confirmation modal - Use ConfirmationModal component instead of plain window.confirm - Delete button only shows when script files exist locally - Includes proper error handling and success/error messages
