feat: rebuild voice agent UI — larger layout, contact card, reconnect, no chips

- Larger orb (w-24), taller transcript (max-h-72), proper scrollIntoView
- On-screen contact confirmation card replaces verbal spell-back
- Reconnect button on connection loss
- Selection chips removed (structured data captured silently)
- Mobile-sticky controls for thumb reach
