Cluster edges created via the pending -> approve path rendered on the top
handle instead of left/right, because the edge and its endpoints lost their
handle information on the way to the canvas.
- Approve resolver (scan.py) now returns each edge's type + source/target
handle. Handle IDs are the bare slot-0 side names ('right'/'left'), the
canonical stored form React Flow resolves to the correct side; a '-t' target
id fails to resolve and falls back to the top handle.
- Frontend injectAutoEdges no longer hardcodes iot/bottom/top-t. It injects
each edge with its real type + handles and bumps the referenced nodes'
left/right handle counts (which default to 0) so the cluster endpoints exist.
Logic extracted to a pure, tested util (applyAutoEdges).
- clusterEdges direct-import path uses the bare 'left' target to match.
Tests: new autoEdges unit tests; updated backend handle assertions.
