Add Dockerfile for containerization

[CodexRaunak]

We need to add a Dockerfile to containerize the PenCraft-Full-Stack-Blogging-Application. This will help ensure consistency across different development and production environments. The Dockerfile should:

1. Use a Node.js image as the base.
2. Set the working directory.
3. Install dependencies for the backend, frontend, and common packages.
4. Build the frontend using the vite build tool.
5. Copy the necessary files.
6. Expose port 3000 and run the backend development server (wrangler dev).

Acceptance Criteria:

1. Dockerfile is added to the root directory of the project.
2. Dockerfile can successfully build and run the application.
