Subject: [PATCH 1/3] Make page_count and current accessible from Twig

There are times when it is necessary to show the page_count and current page in Twig templates (for example, "2/6" to mean "page 2 of 6"). This pull request aims to expose variables `current`, `items_per_page`, and `page_count`.

I am not good with making pull requests, so if there is any mistake, please tell me, and I will try my best to fix it. Thanks!

Subject: [PATCH 2/3] Add @return annotations

I had to use `intval()` because `ceil()` returns a `double` by default, so I wanted to cast it to `int` first.
