Fix: update renderSprites based on user settings in SpriteFactory (#2574)

Resolves #2573
 
## Description:
Fixed an issue where structure icons became smaller after upgrading a
building.
In StructureDrawingUtils.ts, renderSprites was always set to true and
never updated, which caused the code to consistently select the
scaled-down icon. This appears to have been the root cause of the
problem. Since StructureIconsLayer (the caller of StructureDrawingUtils)
updates renderSprites based on settings, I aligned the behavior
accordingly.

```ts
    if (type === "icon") {
      const s =
        scale >= ZOOM_THRESHOLD && !this.renderSprites
          ? Math.max(1, scale / ICON_SCALE_FACTOR_ZOOMED_IN)
          : Math.min(1, scale / ICON_SCALE_FACTOR_ZOOMED_OUT);
      parentContainer.scale.set(s);
    }
```

Here is the video demonstrating the behavior after the fix.
Please see the linked issue for the pre-fix behavior.
