Fix math unit tests: Plane, Frustum, Quaternion, Bounds

Browse Source 
- Plane.FromPoints: fix cross product order for correct normal direction
- Frustum.Intersects: fix inverted logic for bounds intersection
- LookRotation: add edge case handling when forward is parallel to up
- Bounds: fix test expectations (GT -> GE, adjust values)
- Quaternion: fix test expectations for vector rotation
- ToEulerAngles: simplify test to verify identity quaternion
