fix(mock): scale visual-cluster fixtures to the scenario

Browse Source 
The mock Explore clusters were a fixed 10 regardless of scenario, so the "huge"
dev scenario looked sparse next to its large tag vocabulary. Mirror the backend's
k = (n / 20).clamp(5, 30): the huge scenario now surfaces ~30 clusters with a
long-tailed, big-library-sized count distribution, so Explore looks realistic.
