Enhance pagination to make next page visible before ellipsis

[tcrz]

Pull Request

Description

When the current page is the last visible number before the right ellipsis, the pagination should include the next page before the ellipsis to help users scan forward. Example: with many pages, being on page 3 should render “1 2 3 4 … 10” instead of “1 2 3 … 10”.

Current Behavior
On early pages, the window renders a fixed set of numbers and ellipses.
Example with totalPages=10, page=3: “1 2 3 … 10”.

Expected Behavior
When the current page is the last visible number before the right ellipsis (boundary), show one additional page before the ellipsis.
Example with totalPages=10, page=3: “1 2 3 4 … 10”.
