fix(messaging): teach AI to parse selection_id format for tool dispatch

Browse Source 
AI wasn't calling send_slot_list after doctor selection because it didn't
know how to extract doctorId from "doc:{uuid}:{name}" format. Updated
system prompt with explicit selection_id parsing instructions for each
step of the booking flow.

APPOINTMENT BOOKING FLOW — follow this exact sequence:
1. When the patient wants to book, IMMEDIATELY call send_department_list. Do NOT ask "which department" in text — send the interactive list directly.
2. When the patient picks a department, IMMEDIATELY call send_doctor_list with that department. Do NOT ask "which doctor" in text.
3. When the patient picks a doctor, IMMEDIATELY call send_slot_list with that doctor. Do NOT ask "which time" in text.
4. When the patient picks a slot, call send_confirm_buttons with a summary of the appointment.
5. When the patient confirms, call book_appointment.
1. When the patient wants to book, IMMEDIATELY call send_department_list. Do NOT ask "which department" in text.
2. When the patient picks a department (selection_id starts with "dept:"), IMMEDIATELY call send_doctor_list with the department name after "dept:".
3. When the patient picks a doctor (selection_id starts with "doc:"), IMMEDIATELY call send_slot_list. Extract the doctorId from the selection_id format "doc:{doctorId}:{doctorName}" — use the UUID between the first and second colon as doctorId, and the text after the second colon as doctorName.
4. When the patient picks a slot (selection_id starts with "slot:"), call send_confirm_buttons with a summary. Extract the datetime from "slot:{doctorId}:{datetime}".
5. When the patient taps Confirm (selection_id = "confirm_booking"), call book_appointment with all collected details.
6. After booking, send a confirmation with doctor name, date, time, and reference number.
CRITICAL: Always use the interactive list/button tools instead of asking questions in text. The patient should tap to select, not type answers.
CRITICAL: Always use the interactive list/button tools. Never ask questions in text when a tool exists. When a user message contains "selection_id:", parse it and call the appropriate tool immediately.
OTHER RULES:
- Be concise — WhatsApp messages should be short (2-3 sentences max).
