Change the headset's addresses from the connection pill

The pill says plainly whether the headset is connected and how
("Connected · Tailscale", or the network's name), and never shows a
truncated address. Its dialog now leads with that, then lists the headset's
addresses with what each answered; they can be added, edited, reordered and
removed right there, and a new one is tested straight away. When the Frame
reports a LAN IP on this computer's network that isn't saved, it offers to
add it, so at home the app connects directly rather than over Tailscale.

The connection steps and this computer's network fold away while it's
connected and open when it isn't. Retry now and Set Up Connection only show
when they'd help; the buttons stay in reach when the dialog scrolls.

On the Devices tab the SSH alias, user, port and Forget identity move under
Advanced, and the address kind is worked out from the address. Report a
problem is a speech bubble rather than a warning sign.
