fix(Button): fixes behavior of asChild in BrandButton

[qstearns]

mouse moves trigger render cycles in BrandButtons.

when this component reference is unstable it breaks click events unpredictably

---

Note

Extracts a top-level BrandSlot and passes isBrandVariant when asChild is used to correctly inject brand background without unstable re-renders.

• Button (src/components/Button/index.tsx):
  • Refactor/Extraction: Move BrandSlot to a top-level component and reuse it when asChild is true.
  • asChild Handling: Pass isBrandVariant to BrandSlot and set Comp to BrandSlot when asChild to inject the brand background correctly.
  • Rendering: Keep existing brand background span for non-asChild path; child processing unchanged except bypassed when asChild.
