Fixes #5850

The simulator canvas blits straight to the screen through getGraphics(), outside Swing's paint cycle. Lightweight menu popups paint into the same surface, so wherever one overlaps the canvas/skin the next blit overwrites it and it smears. The old workaround repainted open menus after each blit, but translated them by the invoker's X only, which was wrong in landscape and when zoomed.

• installMenu now calls JPopupMenu.setDefaultLightWeightPopupEnabled(false), so popups get their own native window above the canvas.
• Removed the per-blit popup repaint, which would otherwise leave a ghost copy of a heavyweight menu on the canvas.

Not yet verified by eye on Windows 11 landscape.
