pyr0ball 12b56e3153 fix: route logger through UART0 instead of USB_SERIAL_JTAG 
Waveshare's board wires log output through the same UART USB-C port
used for flashing. ESPHome's default hardware_uart for ESP32-S3 is
USB_SERIAL_JTAG, which is a separate physical port on this board,
so log output was going nowhere the flashing tool could see it.
