Update navbar in Blog page

[shristhi-2908]

The navbar in the Blog page is currently hardcoded. To make it consistent across all pages, replace the existing navbar code with the reusable navbar.html component.

Tasks:

Remove the existing navbar code from blog.html

Include the navbar.html component instead

Ensure the styling (CSS) and functionality (JS such as dark mode/hamburger) remain intact

Test responsiveness on desktop and mobile

Expected Outcome:
The Blog page should use the same static navbar component as the rest of the website.
