Return the trips whose stages overlap this booking's location and date window, using the same matching rules as the TripReconciler: case-insensitive location equality and ≤24h date adjacency.

Flow calls this in the post-confirmation flow. When length > 1 it shows a disambiguation picker and calls POST /v1/trips/{tripId}/bookings with the traveler's selection. When length ≤ 1 no picker is shown and the existing reconciler result stands.

Returns an empty list [] when no trips match — not 404. Returns 404 only when the booking ID is unknown or belongs to a different traveler. Travelers without a persisted profile receive an empty list without creating one.
