/**
 * Builds the displayed page items for a 0-based `currentPage` and `totalPages` count.
 * Always keeps the first page plus a constant-width window around the current page. When the last
 * page is known it also pins the last page and collapses gaps with an ellipsis; when it is not yet
 * known (row count still loading) it never pins a concrete last page and ends with a trailing
 * ellipsis instead. The current page is clamped into range so transient out-of-range pagination
 * state cannot produce buttons beyond the available pages.
