feat: implement messaging functionality with real-time updates
- Introduced a messaging module on the backend using NestJS, including repository, service, controller, DTOs, and WebSocket Gateway. - Developed a frontend messaging page with conversation management, real-time message handling, and chat UI. - Implemented `MessageService` for API integrations and `SocketProvider` for real-time WebSocket updates. - Enhanced database schema to support conversations, participants, and messages with Drizzle ORM.
