Add hardware watchdog and QuickMsgScreen

Browse Source 
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.
