[Feature]: Containerize this is project with docker

[Satvik-Singh192]

So, what is it about?

This feature is about containerizing the CollabCanvas project using Docker and Docker Compose.

Currently, the setup is manual and complex, requiring developers to:

• Run the client and server in two separate terminals
• Manually set up and connect to an external MongoDB database

✅ Proposed Solution

Create a docker-compose.yml file that defines three services:

1. client — React application
2. server — Node.js backend
3. db — MongoDB (official mongo image)

🎯 Expected Outcome

A simple, one-command setup:

docker-compose up
