fix(Wings): respect rotations from Rotations module

[minecrrrr]

When rotation is modified by the "Rotations" module, the wings fail to attach to the visual mode

Thanks for the PR! I couldn't find an existing issue tracking this, so a short description would help the reviewers: what the wings look like without the fix (e.g. desync between wing direction and the visible model) and how to reproduce it.

Two small things a reviewer will likely bring up:

• The when (ModuleRotations.enabled) blocks read more naturally as if/else, and the module state is checked twice — a single branch computing both rot and bodyRot would be simpler.
• When the module is enabled but modelRotation/prevModelRotation are null, the code mixes a model-based value with an entity-based one per component; worth confirming that's intended rather than falling back to the entity rotations as a pair.

Nothing needed on the docs side.
