feat(l2,core): battery curve editor and an L2 feedback round

- Battery curve: NodePrefs batt_curve_mv[11] (voltage at 0..100 %, all zeros = built-in LiPo curve, sentinel 0xC0DE0032). ui-core/Battery.h uses it for every percentage. L1: Settings > System > Batt curve list (Left/Right 10 mV, Reset); L2: Settings > Power > Battery curve chart with draggable points and a line at the cell's voltage. - L2: the Nodes map is the full navigation map plus the nodes, Back returns to Nodes; the favourite button is lit while it is one; pinning to the Home dial uses a thumbtack (fonts regenerated); minimap dots follow the accent; arranging tiles shows where they land while dragging; emoji row in Diagnostics > Font. - Sim hooks: sim_open nodesmap / accent@N / homeedit / battcurve.
