Motivation

Dialog.Actions clones each action child to inject compact, uppercase, and spacing props. When callers wrap actions in a fragment, React 19 warns because those props are applied to React.Fragment, which only accepts key and children.

This treats top-level fragments as transparent wrappers so their children still receive the dialog action props, while the fragment itself is not cloned.

Fixes #4794

Test plan

• yarn test src/components/__tests__/Dialog.test.tsx --runInBand
• yarn typescript
• yarn lint-no-fix src/components/Dialog/DialogActions.tsx src/components/__tests__/Dialog.test.tsx (passes with an existing unrelated warning in src/components/__tests__/TextInput.test.tsx)

I also let the pre-commit hook run once. It ran lint, TypeScript, and the full Jest suite; the full suite failed in this sparse/source checkout because src/babel/__tests__/index.js expects lib/mappings.json, which is not present without generating/building lib. The touched Dialog test passed in that run.

On main (6.x) this is already fixed another way: #5076 changed Dialog.Actions so it no longer clones its children, and each Button inside it now takes mode and compact itself. So this change isn't needed on main, and I'm closing it. #4794 stays open, because the 5.0 branch still clones the children, so 5.x apps still see the warning. A fix for that against the 5.0 branch would be welcome.
