Redesign the UI after the fitness reference and replace the logo

Light sage-to-cream ambient backdrop, frosted glass controls and painted
SceneArt landscapes in place of photography. Home becomes a dashboard with a
two-tone greeting, a frosted summary ring, category portraits, an up-next rail
of image-led cards and a floating glass tab bar. The routine library gets an
image header and painted cards; the player gets a scene stage, steps on an
arc, a dotted clock and a night pill with a lime spark. Goals become painted
cards in their own colour.

New logo: a lime sun resting on a ground line under two arcs. The splash
raises the sun and lights the arcs; launcher icons and native splash are
regenerated to match.
