TXBOX - refactor: update package configuration and improve error handling

- Changed package.json to use "tsx" instead of "ts-node" for development.
- Updated "@whiskeysockets/baileys" dependency to version 6.7.24.
- Added error handling for unhandled rejections and uncaught exceptions in server.ts.
- Implemented a reconnect mechanism for WhatsApp connection failures.
- Updated tsconfig.json to use "NodeNext" module and resolution for ESM compatibility.
