Enhancement: Replace default Next.js favicon with project logo

[aliviahossain]

Hello! This is a really well-designed application. 👍

I noticed a small visual improvement that could be made: the application is currently using the default Next.js favicon (the icon in the browser tab).

Proposed Solution:
To improve the project's branding, I suggest replacing this with the official StockVision logo, which is already available in the public/logo.png directory.

According to the latest Next.js conventions, this can be done by copying the logo.png into the app/ directory and renaming it to icon.png. Next.js will then automatically use it as the new favicon.

This is a small change that will give the project a more polished and professional feel. I'd be happy to create a pull request for this!

PLEASE ASSIGN ME THIS ISSUE UNDER THE GSSOC' 25 LABEL. THANK YOU.

@aliviahossain There is a favicon in the app I'm not sure why you're unable to see it.
