- AppShell: h-screen + overflow-hidden for pinned header
- AI chat: input pinned to bottom, messages scroll independently
- Dialler: numpad grid (1-9,*,0,#) replaces text input
- Inbound calls: don't fall back to previously selected lead
- Appointment: use lead.patientId instead of leadId for FK
- Added .env.production for consistent builds
