feat(l2): settings put in one consistent order and look

Settings: Name and Radio first, then Bluetooth, WiFi and GPS side by side
(a tap on each row opens its details: the pairing PIN, the networks, the GPS
screen with a new Options tab for power saving and the fixed position), then
Device, Mesh & data (Adverts & privacy now holds Auto-advert) and System.
Time & units, Power as one group. Row symbols get a column of their own, value
labels are as wide as their text, group headings are uppercase everywhere, the
auto-add node types show only with "By type". SOS in three groups, WiFi with
its switch, Map tools with the layers (Packet flow among them) under the trail.
