Pass DOCKHAND_API_TOKEN to container inventory calls so pipeline_active
and topology animation work after Authentik. Replace ring-buffer-only CDC
stats with minute rollups (no 1000 cap), add 15m/1h/6h/24h window selector
on the Live Changes tab, and poll recent events on an interval.

Add api/cdc_consumer.py: aiokafka background consumer subscribes to the CDC
topics (postgres_sales/mysql_hr/mongodb_supplychain + cassandra/neo4j), parses
Debezium before/after envelopes, keeps a ring buffer and publishes each change
live as type=cdc_change. Endpoints /api/changes, /api/changes/stats, /status.
