Snap monitor scaling up to the nearest clean scale Hyprland accepts

Browse Source 
Hyprland only takes scales where the mode divides into whole logical
pixels (in 1/120 steps), so picking 3x on a 1280x800 QEMU display threw
a red error overlay and silently kept the old scale. Round the request
up to the nearest clean divisor instead, so 3x becomes 3.2x.
