fix: warn of radio pins that can stop the board booting (#34)

Browse source 
GPIO12 is a strapping pin on the original ESP32: high at reset, it powers
the flash at 1.8 V. A CC1101 can hold GDO2 high at power-up, so a board
with RX on 12 bootloops after a power cut until EN is pressed. It was the
default RX pin.

- RX defaults to GPIO35 on the original ESP32. Saved settings keep their
  pins.
- The log warns each time the radio starts, and the radio settings show a
  warning, while TX, RX or MISO is on a pin whose level at reset can stop
  the chip booting (src/BootPins.h, data-src/js/pins.js).
