fix(wokwi): add serial monitor config and USB_SERIAL_JTAG for ESP32-S3

- Add serialMonitor display config to all diagram templates
- Set USB_SERIAL_JTAG attr on ESP32-S3 for built-in USB serial
- Add TX/RX → $serialMonitor wiring for ESP32 (UART-based serial)
- Remove disconnected breadboard parts (wired directly to MCU pins)
