"""Minimal Odoo XML-RPC client for the phone agent.

Creates an appointment *request* in Odoo from a captured call. A request is NOT a
confirmed booking — staff call the patient back to finalize — so by default we write
a CRM lead (a clean "to-do" that doesn't occupy a real calendar slot). Set
ODOO_TARGET=calendar to instead drop a tentative event on the calendar.

Auth + target are all env-driven (see .env.example). Connection is lazy and every
failure is swallowed by the caller's fallback, so a flaky Odoo never drops a request.
