Fix PromptInputLine closing immediately after InputSelector, split SSH domain entry into steps

Selecting a settings item from an InputSelector menu (font size, line height,
color scheme, opacity, scrollback lines, max FPS, SSH domain add) would open
a PromptInputLine that closed instantly, dumping back to the shell — the
Enter that confirmed the InputSelector choice was bleeding into the newly
opened PromptInputLine. Deferring the PromptInputLine open by one tick via
wezterm.time.call_after fixes it. SSH domain registration now asks for name,
address, and username one at a time instead of a single comma-separated line.
