test(gallery): repair stale probe assertions

The committed probes asserted the pre-sprint gallery: default size 3 (now 2/M since 70507b7) and five .famchips rows (card 01's option capsules reuse the class, so six exist). The zoom test now clicks 3x explicitly instead of assuming it as the default, and the family count filters to rows labeled 'screen' so future option-group cards don't break it.
