Add pagination support to ingress list (#915)

* Add pagination support to ingress list

Mirror the egress list pagination: a new --limit flag walks pages via
NextPageToken, prepending each older page so output stays in
chronological oldest-first order. Without --limit, behavior is
unchanged (single API page). JSON output keeps the response-object
shape for compatibility.
