chore: release v0.27.1

Tried on the real IC-7760: the magic packet wakes nothing; Icom's own
mechanism is the network-standby session plus the CI-V power-on, which
OpsLog already does. The MAC store and the WOL sender go, and the changelog
entry with them. The CI-V pump now says once per session that the client
pings are armed — invisible pings read as absent pings.
