calico: bump tigera-operator mem limit 256Mi -> 512Mi (OOM crashloop fix)
The operator OOM-crashlooped on 2026-06-23: it idles at ~246Mi with a ~266Mi
startup spike (re-listing resources to build informer caches), both at/over the
256Mi limit, so the first time the pod restarted it could never finish startup
(exit 137 OOMKilled, leader-elect, OOM, repeat). A latent landmine — the limit
was always too tight; it only bit once the pod restarted. Data plane was never
affected (calico-node 7/7, tigerastatus green throughout). 512Mi gives headroom
(now ~246Mi steady, verified stable 0 restarts). NOT caused by the ESO migration
(which never touched calico); cluster churn was at most the trigger that exposed
the tight limit.
