Device-synced highlights stored POINT CFIs (epubcfi(.../8/1:1)); the overlayer resolves those to a collapsed range and paints nothing, so KOReader-made highlights were listed in the drawer but invisible on the page. mapHighlightRow now builds a renderCfi: a proper RANGE CFI (epubcfi(base,/start,/end)) synthesized from the stored start/end points. It also repairs stale rows: missing ends (old web highlights) and degenerate document-start ends (the old converter fallback) are derived from the start offset plus the selection text's UTF-16 length. All overlay drawing, navigation (showAnnotation), and the post-create/post-edit re-adds use renderCfi. Verified in-browser against live device-synced rows: the paginator's overlayer paints the highlight rects after the fix.
