Fix warning about InteractiveScreen's "uniform size"

[miskatonicstudio]

Godot v4 shows a warning for InteractiveScreens, because they use a scaled collision area (with original size 1x1 units) instead of a uniform one. However, the interaction with screens is based on their size being exactly 1x1.

This is not a high priority task, but if there is a way to fix the warning without breaking the interactive screens, it should be done.
