daemon: use default address + well-known ports for scheme

This ensures the "bound $URL" diagnostic message at startup
always shows the URL scheme handled if not relying on socket
inheritance.

This also avoids duplicate/unused data structures when binding
sockets ourselves, as bound socket names can expand from short
names to longer names (e.g. "0:119" => "0.0.0.0:119").
