feat: add share dialog and typing indicator in messages

- Implemented `ShareDialog` component for sharing content directly with other users.
- Added typing indicator when a user is composing a message in an active conversation.
- Updated `SocketProvider` to handle improved connection management and user status updates.
- Enhanced the messages UI with real-time online status and typing indicators for better feedback.
