[feature]: Add board temperature monitoring and logging.

- Introduced readBoardTemperature() and formatTemperatureMessage() utilities.
- Added print_board_temperature() to log formatted temperature readings via SerialPrinter.
- Registered board temperature as a scheduled entry in scheduler1 and print it periodically in loop1.
- Adjusted scheduler intervals and initialised LED_BUILTIN as output.
