Adds a LEDManager class (src/helpers/ui/LEDManager.h) that centralizes all LED control into one component with begin()/loop() lifecycle and per-pin active-HIGH/LOW polarity support. LED settings are exposed as custom vars (led.status, led.activity) accessible via companion radio binary protocol, CLI set/get commands, and the SensorManager settings interface. Status LED modes: off, boot-30s, slow blink (200ms/4s), always on. Activity LED modes: off, BLE only, LoRa TX only, BLE + LoRa TX. Integrated into 23 board variants, replacing scattered hardcoded digitalWrite calls in onBeforeTransmit/onAfterTransmit/powerOff.
