ExpressivePageTransitionsBuilder class

A page transition using the Material 3 shared-axis (X) pattern, via the official animations package. The incoming route slides in along the horizontal axis and fades through while the outgoing route fades/slides out — the recognizable M3 forward/backward motion between hierarchy levels.

Crucially, SharedAxisTransition.fillColor paints the theme surface behind the moving pages, so the slide never exposes the black void behind the navigator. Honours reduced-motion by collapsing to a plain cross-fade.

Wire it into ThemeData.pageTransitionsTheme (see expressivePageTransitionsTheme) so every pushed route shares one motion language.
