[Sheet] Support ref as prop on Header and expose modal prop

[ravisuhag]

Summary

Sheet has been migrated to Base UI and renamed to Drawer (@base-ui/react/drawer). Some improvements from the original issue still remain.

Completed

• Accept ref as a prop on SheetHeader — All sub-components (DrawerTitle, DrawerDescription, DrawerBody, DrawerFooter) use forwardRef
• Expose modal prop — Available via Base UI Drawer primitives
• API migration — Fully migrated from Radix Dialog to Base UI Drawer

Remaining Improvements

1. Accept ref as a prop on DrawerHeader

DrawerHeader is still a plain functional component that does not forward refs, unlike all other Drawer sub-components.

Moved to Cross-Cutting Issues

The following items have been moved to cross-cutting issues that address them across all components:

• Replace hardcoded CSS values with design tokens (Replace hardcoded CSS values with design tokens #672)
• Accessibility baseline (Accessibility baseline: aria attributes, roles, and semantic HTML #673)
• Animation: prefers-reduced-motion (Add prefers-reduced-motion support for animations #677)
