* [Completer] Fix popup going offscreen by clamping in screen coordinates

The position clamping in applyPopupWidth() was comparing popup->pos()
(parent coordinates) against screen->availableGeometry() (screen
coordinates).  When the parent widget is not at the screen origin the
clamping computed a position in the wrong coordinate space, placing the
popup offscreen.  Convert to global coordinates first, clamp, then map
back to parent coordinates.

* [Completer] Clamp popup from geometry() in screen coordinates

setMinimumWidth() already widens the popup synchronously, so the old
width() < minWidth guard never ran and the popup grew past the right
screen edge. The popup is also a top-level Qt::Popup window, so move()
takes global coordinates and the mapFromGlobal round-trip moved it to
the top-left of the screen. Clamp x from geometry() after
setMinimumWidth() and move(QPoint(clampedX, popup->y())) directly.
