DetailsStep now renders the appointment's visit date/time first (from session_at, falling back to created_at) and an itemized cost table (visit + each service line with its line total) plus the grand total. Extend SessionCardData with session_at, services_total_rials, and per-line price fields already returned by the session API. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
