feat: Implement numbered pagination and pinned posts for blog

This commit introduces a numbered pagination system for the blog, displaying 10 posts per page. It also adds the ability to pin posts to the top of the blog list.

- Implements a numbered pagination partial with corresponding styles.
- Modifies the blog list template to display pinned posts first, followed by paginated posts.
- Updates `config.toml` to use the correct `pagerSize` key for pagination.
