fix: clinicId on all appointment paths + startedAt on call records

- AI chat book_appointment tool: accepts optional clinicId
- Widget booking: passes clinicId from request
- LiveKit agent: passes clinicId from doctor context if available
- Dispose endpoint: sets startedAt/endedAt on outbound call records
  (computed from durationSec). Fixes null timestamps in call history.
