Sebastien Vayrette 8e66430c86 fix: CAN on GPIO 15/16, UART IO on 17/18 — actual hardware wiring
Tee confirmed physical wiring on Waveshare ESP32-S3 board:
- GPIO 15 = CAN TX (SN65HVD230 TXD)
- GPIO 16 = CAN RX (SN65HVD230 RXD)
- GPIO 17/18 = inter-board UART to ESP32 IO

Previous configs (GPIO 2/1, 43/44) were spec assumptions that didn't
match the actual board wiring. GPIO 43/44 are internal to PCB, not
on the header where the transceiver is connected.
