Add hero illustrations using XAML-native vector graphics (shield+lock
for login, person+plus badge for registration). Improve visual design
with gradient backgrounds, icon badges on benefit cards, and refined
spacing/corner radii. Add Enter key handling so pressing Enter in an
input field moves focus to the next field, and pressing Enter on the
last field triggers the primary action (login/register).
