Adjust ESC status light colors for flight modes

Update LED patterns in src/sp140/esc.cpp: FLIGHT_WARNING now uses LED_YELLOW instead of LED_GREEN, and FLIGHT_CRITICAL now uses LED_RED instead of LED_YELLOW. This aligns the visual indicators with expected severity levels (warning -> yellow, critical -> red).
