The hero icon is now the optimistic on/off toggle with a tooltip,
replacing the connect block and the progress lines beneath the hero.
The disconnected cross is drawn grey rather than red, and action
errors expire after a couple of seconds instead of sticking forever.

The `Bar` uses a `Repeater` when building out the models. This has the
effect of marshalling the configuration, and causing JSON arrays to
become sequence wrappers.
A couple of the plugins had been checking for the existence of array
values with `Array.isArray`, which fails for the sequence wrappers,
causing the values to be ignored. This breaks associated functionality
(the "hide" and "pin" actions in the systray had stopped working, as had
exit node selection in Tailscale).
Switching the guards to use `instanceof Array` works correctly for
sequence values (as well as arrays).
