// CHANGE: replaced the old hand-rolled inline table with <TripTable/>.
// CHANGE: TripFormModal now imported from the barrel (@/src/Components/Trip)
// instead of a direct path — avoids the Tripformmodal.tsx case-sensitivity
// mismatch that breaks on case-sensitive filesystems (Linux/Docker builds).
// CHANGE: removed the local ArchivedTripsModal wrapper (it duplicated what
// the new ArchivedTripModal already does — search bar + table + detail) and
// removed the ArchivedTripList import; now renders <ArchivedTripModal/>
// directly.
