Filter the authenticated customer's appointments with the standard v2 filter/order_by/page body. Any response field — including dotted paths into related records, e.g. uuid, status, scheduled_start_dt, distribution_center.code, domestic_shipment.uuid, domestic_shipment.shipment_id, import_drayage.uuid — can be used in filter conditions, except container.*: use the top-level container_uuid parameter, which matches the container whether it is linked to the appointment directly or through its import drayage.

All datetimes are FC-local and naive: filter values are compared as local time and timestamps are echoed back exactly as stored (no Z, no offset).
