feat: telephony overhaul + appointment availability + Force Ready

Telephony:
- Track UCID from SIP headers and ManualDial response
- Submit disposition to Ozonetel via Set Disposition API (ends ACW)
- Fix outboundPending flag lifecycle to prevent inbound poisoning
- Fix render order: post-call UI takes priority over active state
- Pre-select disposition when appointment booked during call

Appointment form:
- Convert from slideout to inline collapsible below call card
- Fetch real doctors from platform, filter by department
- Show time slot availability grid (booked slots greyed + strikethrough)
- Double-check availability before booking
- Support edit and cancel existing appointments

UI:
- Add Force Ready button to profile menu (logout+login to clear ACW)
