In paginated fixed-layout mode (PDF / fixed-layout EPUB) with fit-width zoom, a
page taller than the viewport makes the renderer host scroll vertically. Turning
the page kept the previous page's vertical offset, so the next page opened
scrolled to the end instead of the top. The bug only shows on WebKit
(Linux/iOS/macOS), which preserves the scroll offset across the page content
swap; Blink (Android/Chrome) resets it to zero.
Bump foliate-js to the fix (readest/foliate-js#34): reset scrollTop on a page
turn only. Add a unit test for the new computePaginatedScroll helper.
