Resolve out-of-range verse refs to the nearest preceding segment

[alex-rawlings-yyc]

The host's next-verse button emits verseNum + 1 without clamping, so bumping forward from a chapter's last verse delivered a verse past the chapter's end; the loader only resolved verse-0 refs, and the segment window's anchor fallback jumped to the start of the book. Any unmatched verse now resolves to the nearest preceding segment start in its chapter, so the view holds at the chapter's end (and a verse inside a merged multi-verse segment resolves to its owning segment).
