feat: update Socket.IO polling configuration and enhance Docker setup

- Modified docker-compose.prod.yml to clarify WebSocket production settings.
- Added environment variable NUXT_PUBLIC_SOCKET_IO_POLLING_ONLY to Makefile for production and development modes.
- Refactored nuxt.config.ts to improve Socket.IO polling behavior based on new environment variable, allowing for dynamic configuration without rebuilds.
