AppointmentMeeting

An appointment meeting represents the conferencing details for an appointment. Meetings are created asynchronously after an appointment is scheduled, so the `status` field reflects where the meeting is in its lifecycle. Meeting details such as `join_url` are populated only once the status is `created`. The `host_url` field is a proxy URL on the account's booking domain (the canonical SavvyCal host, or an active custom domain when one is configured) that the meeting host follows to start the meeting. **Treat this URL as a credential — anyone with it can start the meeting as the host.** It is valid through the appointment's end time + a 24h grace window, after which it returns 410 Gone. SavvyCal refreshes the underlying conferencing-provider URL transparently behind the proxy, so the proxy URL generally remains stable across `appointment.meeting.updated` events. It may change if SavvyCal rotates the underlying token (e.g., for security reasons) or when the meeting is replaced — a brand-new meeting with a new `id`, which happens when a reschedule routes the appointment to a different host on the account. Listen for `appointment.meeting.updated` and `appointment.meeting.replaced` to keep stored copies fresh. `host_url` is null when the meeting is not yet `created` or when the conferencing provider has no distinct host start URL (e.g., Google Meet uses a single shared URL).
