fix: persist analytics DB to named volume in all compose configs

FOXMEMORY_ANALYTICS_DB_PATH was defaulting to /data which had no volume
mount, causing stats to reset on every container restart.

- compose.one.yml / compose.split.yml: point to /qdrant/storage (existing vol)
- compose.graph.yml: add foxmemory_analytics_data volume mounted at /data
- .env.example: document the var with a note
