Move pagination logic to preserve filter query parameters (school_id, order_by, asc, per_page) when navigating between pages. - Added QueryParams field to Pagination struct and pageURL() helper - Server-side: buildListCoursesQueryParams() encodes active filters into pagination links as query string - Client-side: setupPaginationLinks() intercepts pagination link clicks, reads current filter state from DOM selects, and constructs full URLs with all parameters preserved - Added data-paginated/data-base-url/data-current-page attributes to pagination nav for JS targeting Closes #1
