fix(deploy): the home end dials the instance's server by its address (ADR 0032, D11)

A tunnel that fails to come up takes Jellyfin's internet with it, as
linuxserver/wireguard's client mode deletes the default route. Named by
learn.halkyon.eu, the endpoint needed DNS to come up, which the home end
starting or waking hasn't always got yet; by its address the tunnel comes
up whatever the network does. Closes ADR 0032's open point.
