feat(machine): redesign idle screen with circular touch zones

Full-canvas layout: brand zone with logo/badges/balance at top,
two circular touch zones (Buy=bitcoin orange, Sell=green) with
zone-glow animation. Show per-flow commission rates (Buy/Sell).
Move light/dark toggle to App.vue for omnipresence.
