Add activity feed API

[alphatroya]

TL;DR

Created a basic Express server with a mock activity feed endpoint.

What changed?

• Implemented a new Express server in server.js
• Added a /feed endpoint that returns mock activity feed data
• Included sample activity feed entries with different types of user actions

How to test?

1. Install dependencies: npm install express
2. Start the server: node server.js
3. Send a GET request to http://localhost:3000/feed
4. Verify that the response contains the mock activity feed data

Why make this change?

This change sets up the foundation for a backend service that will provide activity feed data to the frontend. It allows for initial testing and integration of the activity feed feature without requiring a full database implementation.
