Adds an "AI Call" option alongside Call/SMS/Chat that places an outbound call where Lisa converses live with the patient via Twilio speech gather + TTS, using the same conversational AI as chat. Includes a separate, user-editable Call Template (Settings > AI Chat/Call Settings) so the call greeting can be customized independently of SMS templates. Also fixes the outbound-call webhook URL to always use the fixed public Twilio hostname (CLOUDFLARE_HOST) instead of deriving it from the triggering request, since staff-browser requests arrive over the LAN-only hostname, which Twilio can never reach.
