/**
 * Dashboard Page — redesigned 3.0.5
 *
 * Layout principles:
 *
 *   - One header row: page title + date-range picker. Welcome card is
 *     dismissible (state stored in localStorage so the operator doesn't
 *     see it every time after onboarding).
 *
 *   - KPI strip: five high-signal cards in a single row with period-
 *     over-period deltas from `/reports`. Removes the duplicate
 *     "Pending Bookings" card the old design had at top + side, and
 *     adds tooltips for the confusable "Booked vs Collected Revenue"
 *     pair operators routinely conflate.
 *
 *   - Main grid: charts on the left (Bookings Overview + Status +
 *     Destinations), operational widgets on the right (Upcoming
 *     Departures, Pending Payments).
 *
 *   - Tertiary: Recent Bookings + Quick Actions full-width at the
 *     bottom. Quick Actions also surface as compact icon buttons in
 *     the page header for faster access from anywhere on the page.
 *
 *   - AI Today's Brief is gated on AI module enabled (see
 *     TodaysBriefCard.tsx) — never renders a "buy AI" upsell.
