// Bookings tab columns — copied from app/(dashboard)/bookings/page.tsx,
// minus the `eventId` column (this list is already scoped to one event via
// urlParams.filters). Cancel/refund stay on their existing flows — an
// organizer cannot cancel a single booking either (business-rules.md), only
// check-in is exposed here, mirroring the host's own attendance action.
// `search` is a filter-only synthetic column (hideInTable) — its value
// round-trips as filters.search, matched server-side (adminList in
// bookings.service.ts) against booking code and guest first/last name, the
// same lookup a host's attendance search covers.
