/**
 * Server-side data resolver for the dashboard PDF report.
 *
 * Each section is gated on its widget id being present in
 * `config.widgetIds`, so a report that only includes the pipeline
 * funnel runs ONE query instead of the full dashboard panel. Keeps
 * cold-call latency low even when the actual port has hundreds of
 * berths.
 *
 * Lives in its own file (not inside dashboard.service.ts) so the
 * report-builder concerns — what widget ids map to what fetcher,
 * which fields the PDF shape requires — stay scoped to the
 * report-side surface, not the dashboard UI.
