Autosave posts to its own endpoint surface lock loss immediately

Previously piggybacked on the main form's action and relied on a
.js.erb response to update #flash; now posts to the dedicated
autosave route with an explicit _method=put override, and reacts to
a 423 by stopping the timer and showing a persistent banner rather
than letting the next Save discover the conflict on its own.
