fix: appointment/enquiry modals + team performance fallback

- Appointment form: converted from inline to modal dialog, removed Returning Patient checkbox
- Enquiry form: converted from inline to modal dialog
- Active call card: removed max-h-[50vh] scroll container, forms render as modals
- Team Performance: fallback agent list from call records when Ozonetel unavailable
- NPS/Time sections show placeholder when data unavailable
