grid: force viewport repaint on resize to fix tiled blank-out

Browse Source 
Qt Wayland buffer goes stale after compositor-driven resize events
(Hyprland tiled geometry change). FlowLayout reflowed thumbs but the
viewport skipped paint until a scroll or click invalidated it, leaving
the grid blank. ThumbnailGrid.resizeEvent now calls viewport().update()
after reflowing so the buffer stays in sync.
