Keep an offline Moonraker printer from freezing startup (#16668)

Browse Source 
Moonraker discovery asked the printer for its name before announcing
it, on the GUI thread, with a 5 s connect timeout. When the selected
printer was off, the window ignored input for 5 s after every launch
and the Home page stayed white.

The request never produced a name. It read machine_name or hostname
from /server/info, and Moonraker sends neither there. Discovery now
announces the preset model name without asking the printer.
