- Live Share tool: add scrollbar, drop non-clickable section headers and
the one-shot "Share now" (keep Auto-share toggle; manual share stays on
the Map). Ellipsize the "To" target so long names don't wrap.
- Move "Track loc" (receive) from Settings into Live Share.
- Map: 2-char contact labels (distinguishable); drop "press" hint from the
Home Map page status line so it fits on OLED.
