fix(led): swap WiFi(play)/LAN(wifi+eth), LAN carrier via CLAWD_ETH_IFACE, faster alarm

- WifiLed drives play; LanLed drives wifi+eth pair (matches panel silkscreen)
- hasLanCableCarrier(): CLAWD_ETH_IFACE-only carrier when set (reliable unplug)
- LAN poll 1s; config.activated persisted for immediate setApps on boot/reconnect
- setApps double vfdOn alarm after 50ms for slow OpenVFD
- Clear activated + setSetup on credential errors
- install.sh env comment for CLAWD_ETH_IFACE
