lowBatIndex(), autoOffIndex(), gpsIntervalIndex() each called
getNodePrefs() independently without null check, while renderItem()
had its own guarded copy. Added null checks consistent with the rest
of the class. Also initialize _node_prefs to NULL in UITask constructor.

Replace linear voltage-to-percent formula with a LiPo discharge curve
lookup table and linear interpolation. The curve is then rescaled so
that low_batt_mv (configurable shutdown threshold) maps to 0% and
4200mV maps to 100%, preserving the non-linear shape regardless of
the chosen threshold.

Filter contact list to ADV_TYPE_CHAT only — excludes repeaters, rooms,
and sensors which cannot receive direct chat messages.

Favourite contacts (flags & 0x01 set by companion app) appear at the
top of the contact picker, marked with '*'. Non-favourites appear
below. The favourite bit is already synced by the existing protocol
via CMD_ADD_UPDATE_CONTACT — no protocol changes needed.

Watchdog: nRF52840 hardware WDT with 30s timeout, runs during sleep.
Resets device if main loop stalls for >30s. Pets in every loop()
iteration so normal operation never triggers it.
QuickMsgScreen: new UI screen accessible from home screen pages.
Two-phase UI: contact picker (shows all contacts with hop count),
then predefined message picker (location, I'm OK, need help, on my
way, ETA 10min, ETA 30min). Location message uses live GPS fix if
available. Sends via the_mesh.sendMessage() and shows sent/error alert.

Save last known unix timestamp to /rtc_save on shutdown and restore it
on startup, so the clock shows correct time immediately after restart
without waiting for GPS fix.

- CPU sleep: board.sleep(0) in main loop puts NRF52 into WFE/sd_app_evt_wait
between iterations; wakes on any interrupt (radio, BLE, timer). Largest
power saving of the three changes.
- VBAT_ENABLE gating: voltage divider now powered only during ADC read
(HIGH for 10ms, then LOW). Previously stayed HIGH continuously.
Fixed in both variant.cpp (init) and WioTrackerL1Board::getBattMilliVolts().
- LED off with display: PIN_LED is cleared when auto-off triggers and
restored (handed back to userLedHandler) when display wakes. Avoids
idle LED current draw during screen-off periods.

* room server: added RegionMap, and new CommonCLI wiring, default_scope handling
* sensor: only minimal RegionMap wiring. Still needs work to handle default-scope
The companion_radio example was not restoring the GPS enabled/disabled
preference from flash after reboot. The preference was being saved
correctly when toggled via the mobile app, but on boot,
sensors.begin() -> initBasicGPS() unconditionally sets gps_active=false
and nothing subsequently restored the persisted state.
Added applyGpsPrefs() (matching the pattern in simple_repeater,
simple_sensor, and simple_room_server) and call it from main.cpp
after sensors.begin() to ensure the GPS hardware is initialized
before the saved preference is applied.
