feat(icom): Wake-on-LAN for a deck that sleeps with its server

A 7760 switched fully off takes its LAN server down, and no session means no console and no ON button — the one thing remote operation cannot tolerate. The rig's MAC is learned from every login and persisted; when a dial finds nobody home, the magic packet goes out to it before the next attempt. The rig wakes into standby, the session opens, and the ON button does the rest.
