nfrunlite reconnect popup dismiss via a11y click window-relative coords

Untitled #32770 reconnect popup in nfrunlite: a11y invoke fails (treated as blocker). BM_CLICK fails (UIPI). Solution: EnumChildWindows -> Button, GetWindowRect -> window-relative coords (subtract popup rect!) -> wkappbot a11y click <grap> --x cx_rel --y cy_rel. win-click is DEPRECATED (prints suggest+exits 1). Bug: passing raw screen coords without subtracting popup origin causes off-target clicks when popup not at (0,0).
