Fix QdrantStore.all_records missing with_vectors=True

Qdrant's scroll() defaults to returning only payloads, not vectors.
Without with_vectors=True, all 1963 records had empty embeddings,
causing community detection to fail (0 communities) and topology
to show insufficient_data. Now 1959/1963 records have 1024-dim
embeddings and 1844 communities are detected.
