feat: add Sidebar onNavigate callback and DataTable fillHeight prop

Sidebar: add optional onNavigate prop so consuming apps can intercept
and remap navigation paths instead of relying on internal React Router
links.

DataTable: add fillHeight prop for flex-fill layouts with scrolling
body. Make the table header sticky by default so it stays visible
during vertical scroll.
