feat(embeddings): use the latent-constellation mark for the block icon

Replaces the scatter-plot-on-axes placeholder with a centre node, four
neighbours, and the rays between them — a point and its nearest neighbours
in embedding space, which is what the block actually produces. The axes
mark read as a generic chart and said nothing specific to embeddings.

Nodes are filled so they hold their shape at small sizes. The rays carry
less weight than the nodes to keep the hierarchy, but at 1.6/0.9 rather
than the 1.4/0.75 they were drawn at, so they do not thin out to loose
dots in the 14px block-search row.

Kept byte-identical between the app and docs icon sets.
