Adding new twitter link, improving some pages

[Pushpa472]

@dohinafsWe should add a new Twitter link to the "About Us" page and enhance its overall appearance for a more engaging presentation.

The footer on the offer page needs to be visually improved to match the appearance of the homepage, and the light mode feature is not functioning properly.

The blog page currently lacks a footer section; we should add one to enhance the overall design and user experience.

On the contact page, we should increase the font size in the footer section to improve its visual appearance

The "X" symbol on the login page is not functioning properly when clicked; we need to fix the bug.

I would like to enhance the copyright policy page for better clarity and presentation.
