Add a footer component to the website

[aliviahossain]

The web application currently lacks a footer section. A footer is a standard component that provides users with important links and information, such as copyright details, contact information, and navigation links, improving the overall user experience and professional appearance of the site.
I propose creating a new, simple footer component that will be displayed on all pages.
