Capture full appointment details + validate dates in-call

In-call (system prompt + per-call calendar injection):
- Gather full name (prompt asks for last name if only first given).
- Confirm the caller-ID number; if declined, use the number the caller gives.
- Ask for and LOG insurance only — never promise/confirm/deny coverage or
  treatment based on it; staff verify on callback.
- Validate the requested date against an injected 45-day calendar (recomputed
  per call since the server is long-running). Push back on impossible/mismatched
  dates, e.g. "Monday lands on the sixth — would you like that date?".
- AGENT_NAME=AVA; 4s grace pause before hang-up (HANGUP_DELAY_SECS).

Logging (post-call extraction -> Odoo):
- Extract full name, phone_confirmed, chosen callback (caller-ID or alternate),
  insurance, reason, and preferred time annotated with a resolved YYYY-MM-DD
  date (today's date is fed to the extractor).
- odoo_client: insurance row on the lead note (log only — staff verify).

.gitignore: ignore rotated avc_run.log* files.
