fix(led,provision): AP forces WiFi(play) off; LAN uses carrier+operstate

- Monitor: every tick in ap state led.off() so play never stays on with hotspot
- hasLanCableCarrier: _ifacePhysicalLinkUp (carrier=1 and operstate not down)
- When end0/eth0 exist but link down, return false (no fallback to hasWiredCarrier)
- LAN poll 500ms
