[Dialog] Forward additional Base UI props

[ravisuhag]

Summary

Dialog wraps Base UI Dialog. Migrated successfully with nested dialog animation support. Some hardcoded CSS values and missing prop forwarding remain.

Completed

• API migration — Fully migrated to @base-ui/react Dialog
• Design tokens for colors, spacing, radius, shadows, fonts, z-index — CSS extensively uses --rs-color-*, --rs-space-*, --rs-radius-*, --rs-shadow-*, --rs-font-*, --rs-z-index-* tokens

Remaining Improvements

2. Use CSS custom properties for animation values

Animation durations and easing functions should use CSS custom properties for theming consistency.

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)
• Animation: prefers-reduced-motion (Add prefers-reduced-motion support for animations #677)
