patches: fix Corfu completion tracking in Zoom

Fget_char_property with a buffer as OBJECT checks text properties
only.  Corfu highlights the selected candidate (corfu-current) via
an overlay, not a text property, so the scan always returned -1 and
Zoom focus stayed on the first line.

Pass cf->selected_window instead of cw->contents so that overlays
are included in the property lookup.  Vertico uses text properties
and is unaffected; child-frame completion frameworks that use overlays
(Corfu, Company-box) now track correctly.
