Merge: rename 'tag cloud' to 'visual clusters' across the stack

Disambiguate the Explore feature naming: the visual k-means cluster view was
named tag_cloud/tagCloud/TagCloud everywhere while the actual tag list is
explore_tags, which was easy to confuse. The cluster side is now
visual_cluster/visualCluster/VisualCluster (command, types, store, DB cache
table, and the ExploreView component); the tags side and the user-facing
"Tag Cloud" label are unchanged. Includes a mock-fixture fix so the dev
"huge" scenario surfaces a realistic field of clusters.
