The manufacturer does not belong to a design (operator ruling); it lives on
FactionProductData and branding is derived, never stored on the design.
- Delete ItemData.cs key 3 (Manufacturer), with a retired-key comment.
- AetherDb census now attributes a design's maker to the first product (in
record-key order) that sells it, matching ItemManager.Brand's rule; a
design no product sells shows "(none)".
- AetheriaStoresTests' catalog fixture moves its Manufacturer reference onto
a FactionProductData selling the design, and FactionIsASingletonInstance
reads it from there.
- mutation_tests.py gets a paired mutation for that fixture wiring.
