Settings: put Emulate USB Keyboard in the Network tab

It existed only in the in-game pause menu, which made the On-Screen Keyboard hotkey's own
message a dead end: it tells you to turn this on in Network settings, and there was nothing
in Network settings to turn on. Reported from Discord after exactly that.

Same Settings.usbKeyboard field as the in-game row, so the two stay in sync, and indexed for
settings search.
