ddadmin 39df4f2469 fix(monitoring): add missing ClickHouse Prometheus port and fix dashboard queries
- Add port 9126 mapping for ClickHouse Prometheus metrics endpoint
  (was configured in prometheus_ch.xml but not exposed in docker-compose.yml)

- Fix CPU Usage panel: use delta() instead of rate() for gauge metric
  ClickHouseProfileEvents_OSCPUVirtualTimeMicroseconds is a gauge, not counter

- Add explicit datasource blocks to dashboard queries for consistency

ClickHouse ProfileEvents metrics correctly use rate() — they are counters.
Warning about missing _total suffix is expected (ClickHouse naming convention).
