Remove update-right-status defer hack, call PromptInputLine directly

The real bug was the invalid initial_value field (fixed previously),
not Enter bleed-through from InputSelector. The defer-via-status-tick
workaround left a gap (up to the status update interval) between the
InputSelector closing and the PromptInputLine actually capturing
keyboard input -- during that gap the underlying shell was visible
(the reported flash) and any keystrokes typed during it went to the
shell instead of the field. This is especially damaging for the
3-step SSH domain flow, where hitting the gap on any step submits an
empty line and the whole entry is silently cancelled without saving.
Calling perform_action synchronously, as before the call_after/defer
detour, removes the gap entirely.
