fix: center splash logo and wordmark (stack was sized to children)

Browse Source 
Wrap AnimatedBuilder in SizedBox.expand so the Stack fills the full
Scaffold body; alignment: Alignment.center now centers within the whole
screen instead of within the wordmark-sized intrinsic box.

Adds a regression widget test (test/ui/splash_screen_test.dart) that
asserts the wordmark dx is within 1px of screen-center at 1500ms into
the animation.
