Add LiPo battery monitoring with ESP-NOW cache and dashboard API.

Slaves report pack voltages every 30s; the master caches them for fast BATTERY_STATUS reads. goTool exposes REST/WebSocket and shows values in the dashboard, with a nanopb fix so optional lipo submessages encode. Co-authored-by: Cursor <cursoragent@cursor.com>
