Can I add pagination to individual blog posts in my twig file?
That is the exact feature of the Book module.
Book module overview
You can configure which types are allowed to be added as book pages. There is a Block you can place on Book pages to show Book navigation and Previous/Next links (it obeys the Book pages order).

Regular Views don't have a feature to center the Pager around a pagination placement.
A custom solution can be created to add that, but there are also modules you can check out that may help:
