Add type annotations and improve script services

Enhanced type safety and documentation in several files, including adding explicit type annotations for script objects and function parameters. Improved error handling and code clarity in scriptDownloader.js, and updated autoSyncService.js to remove unnecessary cron job options. Refactored prisma.config.ts for schema configuration and updated server.js to support backup storage and improve parameter defaults.
