Moved button handling logic to ESP32Board - this has the added benefit that repeaters will also wake up when you press the button (they do not currently). |

@fschrempf Actually basically all devices are low when pressed. Updated the code accordingly. On my Heltec v4 the screen turns off when I disable bluetooth. |

Use millisHasNowPassed() (2's complement safe) instead of direct comparison, consistent with the repeater's sleep timing logic. Co-Authored-By: Wessel <[email protected]>

Summary
Adds power saving to the companion radio when BLE/WiFi is disabled by the user. When the serial interface is off (and GPS is not enabled), the device enters ESP32-S3 light sleep for 30-minute intervals, significantly reducing power consumption for battery-powered companion nodes that are left running as pure relays.
Changes
Light sleep in companion radio (
examples/companion_radio/main.cpp)serial_interface.isEnabled()is false and GPS is offWiFi radio actually turns off (
src/helpers/esp32/SerialWifiInterface.cpp/h)disable()now callsWiFi.disconnect(true)andWiFi.mode(WIFI_OFF)to power down the radioenable()reconnects using stored SSID/password credentialsdisable()only set a flag — the WiFi radio stayed powered onButton wakeup with correct polarity (
src/helpers/ESP32Board.h)enterLightSleep()accepts optionalpin_wake_btnparameter (backward-compatible)GPIO_INTR_LOW_LEVEL) for button — correct for active-LOW buttonsANY_HIGH) for LoRa DIO1 only — these can't share a mask since they need opposite trigger levelsPending work detection (
examples/companion_radio/MyMesh.cpp/h)hasPendingWork()checks outbound packet queue to avoid sleeping while packets are queuedNotes
