PINS_ACTIVE_LAYOUT

#define PINS_ACTIVE_LAYOUT   sense_board_pins::TC_Board

TC (Thermocouple) Hotfire state machine — ESP32 PCB.

Same state machine as PT Hotfire: Waiting for Server → Active → Standalone Abort (and back to Active on clear). Sends heartbeats, streams thermocouple/sensor data to server or to actuator controller in abort. Uses TC_Board pin layout and BoardType::THERMOCOUPLE.
