fix(tests): align wave1-a poolside test with #10216 probed catalog

#10216 published Poolside's two authenticated-probe models
(poolside/laguna-xs-2.1, poolside/laguna-s-2.1) as static seeds, but the
wave1-a free-tier test still asserted 'no invented static model ids'
(entry.models === []), failing every open PR. Separate poolside from the
empty-models assertion and pin its probed catalog explicitly so a future
catalog change is a deliberate update, not a silent drift.
