Add optional row FLIP animation with spring/bezier config

[dbdsgt]

Summary

Add opt-in row animation (enableRowAnimation) using hook useRowFlip for automatic FLIP animations when rows are sorted, filtered, or shuffled. Supports spring and cubic-bezier transition types with configurable parameters. Respects prefers-reduced-motion via useReducedMotion hook. Reorder animation demo to place action toolbar below the bezier/spring configuration panel.

• Implementation: Pure CSS transform-based FLIP via useRowFlip hook (no framer-motion layout dependency at runtime). Uses useLayoutEffect to capture positions before paint, then applies inverse transform + CSS transition.
• Performance: Only the transform and opacity properties are animated (GPU-composited), avoiding layout recalculations. A cleanup timeout resets inline styles after animation completes.
• Opt-in: enableRowAnimation defaults to false — no performance cost unless explicitly enabled.

New Exports

• RowAnimationConfig type
• enableRowAnimation / rowAnimationConfig props on DataTable
• useReducedMotion hook (public)
• useRowFlip hook (public)
