update imgui + node editor (fix combo & color popup placement in node editor canvas)

pthom · pthom · commit 7a98e415baed · 2026-04-30T15:22:56.000+02:00
- imgui-node-editor: BeginWindow hook fix HasFlags typo so SetNextWindowPos
  positions are translated from canvas-local to screen
- imgui: BeginComboPopup short-circuits FindBestWindowPosForPopupEx inside
  the node editor canvas (avoids mixing canvas-local bb with screen-space
  r_outer, which mis-anchored combos when the canvas was zoomed out or
  the node moved up)
