Remote clients reach the backup server over wireguard only on its
internal address; waiting for the wakeonlan network address never
ended there, so htz.mails and the mseibert nodes had no backup since
2026-01-07. The wait now gives up after ten minutes.

Sleeper now exposes the full `/usr/bin/wakeonlan -i <broadcast> <mac>`
invocation as wol-sleeper/waker_command; waker reads that instead of
rebuilding the command line itself. Adds the `-i <subnet-broadcast>`
flag so magic packets reach sleepers on a different L2 segment than
the waker.
