docs(codelab): add BigQuery Studio graph visualization to the query step#276

Adds a 'Visualize the graph in BigQuery Studio' subsection to *Query the
decision trace*, showing the materialized agent_decisions_graph rendered in
BigQuery Studio's Graph view from a GQL path query. The codelab previously
had no graph-viz image (the same screenshot the blog uses in its access step).
The example query is dataset-qualified (GRAPH ${DATASET}.agent_decisions_graph)
to match the codelab's other GQL, and the caption avoids hard-coding node/edge
counts so it does not drift from the screenshot.
Notebook regenerated (now embeds 3 base64 images); --check passes; claat
export builds clean with 3 images copied; focused tests pass (12).

Summary
Adds a graph-visualization screenshot to the periodic-materialization codelab's Query the decision trace step. The codelab previously had no graph-viz image — only the Conversational Analytics card — even though the companion blog shows this same screenshot in its access step.
