List a carrier's lane preferences
Return every CarrierLanePreferenceH3 row for the given carrier, joined with its Lane row so origin/destination city+state come back inline. Filter with `is_active=false` to pull only disabled lanes (the re-enable surface on the carrier detail page). Admin-only — the response is what the PATCH toggle endpoint modifies, so viewing is gated the same way as editing.
**Authentication:** Bearer token required.
